Do you see any differences from an equation when you add or subtract numbers to both sides of the inequality sign?

No, the process is exactly the same.
However, when you multiply or divide, you must be careful: if you multiply or divide by a negative number, the direction of the inequality must be changed, for example:
-x + 3 > 15
(multiply by -1)
x - 3 < -15

How is finding the solution to an inequality different from finding the solution of an equation?
Solving for an inequality requires an additional step. First you solve as if for an equation, then you need to find which numbers give greater than and less than. The easy way to do this is to put in 0 for the variable and see where the values go greater or less. Example: What is the inequality table for 5x=20? when x=4 the equation balances. if x=0 then the left side is less than 20, so all numbers from 4 towards 0 are going to give "less than" values, so all numbers less than 4. The table is {x|(-∞,4),4,(4,∞)}■
What prime numbers satisfy the inequality 17 x 44?
There is no inequality in the question!
How do you subtract decimal numebrs?
If you can subtract whole numbers you can subtract decimals. Forget about the decimal for a sec and subtract the numbers as if they were whole numbers. 2.5 -1.4 =1.1 hope this helps and if not yahoo usually has good examples.
What is the difference between the solution set for an equation and that of an inequality?
A linear equation is any equation involving one or two variables whose exponents are one. In the case of one variable, one solution exists for the equation. For example, with 2x = 6, x can only be 3. A linear inequality is any statement involving one or two variables whose exponents are one, where inequality rather than equality is the center of focus. For instance, with 3y < 2, the "<" represents less than and the solution set includes all numbers y < 2/3. welcome:)
Is it possible to check all the numbers that are solutions of an inequality?
Not unless you have an infinite amount of time as there are an infinite amount of numbers that are solutions to an inequality.
What is a set of numbers that makes the equation or inequality true?
It is the solution set.
Lets say you have a equation can you subtract x from x?
No, you need to find out the numbers to subtract then subtract.
How is solving an inequality different from solving an equation?
In solving an inequality you generally use the same methods as for solving an equation. The main difference is that when you multiply or divide each side by a negative, you have to switch the direction of the inequality sign. The solution to an equation is often a single value, but the solution to an inequality is usually an infinite set of numbers, such as x>3.
How do you work out the differences in between numbers?
Subtract the smaller number from the bigger number.
What has 4 numbers in it 3 variables and 1variable that's a fraction?
It could be an expression or an equation or inequality.
What is a comparison of two numbers or expressions using symbols?
Depending on the comparison operator used, that's either an equation, or an inequality.
How to do inequality?
It's the same thing as solving an equation, the minor difference is to change the inequality sign when the numbers change signs(i.e negative to positive to negative).
What is number sentencs?
A number sentence is typically an equation or inequality expressed using numbers, and common symbols.
What is a number sentence?
A number sentence is typically an equation or inequality expressed using numbers, and common symbols.
What is the equation for 45 less than 95?
First of all, if you have "Less than" or "Greater than" between your numbers, it means that you have an inequality, not an equation.The inequality is: 45
In what way is an inequality different from an equation?
In that it uses an inequality sign (less then, greater than, less-than-or-equal, greater-than-or-equal) instead of an equality sign. When solving, special care must be taken - when multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality sign changes.
Why does an inequality have 2 solutions?
An inequality, like an equation, can have a different number of solutions depending on the inequality and the domain.For example, x2< 0 has no solutions if the domain is the real numbers.x< 5 has only one solution ( = 4) if the domain consists of the squares of positive even numbers.x < 5 has infinitely many solutions if the domain is the rational numbers or real numbers.An inequality, like an equation, can have a different number of solutions depending on the inequality and the domain.For example, x2< 0 has no solutions if the domain is the real numbers.x< 5 has only one solution ( = 4) if the domain consists of the squares of positive even numbers.x < 5 has infinitely many solutions if the domain is the rational numbers or real numbers.An inequality, like an equation, can have a different number of solutions depending on the inequality and the domain.For example, x2< 0 has no solutions if the domain is the real numbers.x< 5 has only one solution ( = 4) if the domain consists of the squares of positive even numbers.x < 5 has infinitely many solutions if the domain is the rational numbers or real numbers.An inequality, like an equation, can have a different number of solutions depending on the inequality and the domain.For example, x2< 0 has no solutions if the domain is the real numbers.x< 5 has only one solution ( = 4) if the domain consists of the squares of positive even numbers.x < 5 has infinitely many solutions if the domain is the rational numbers or real numbers.
