This is quite similar to solving equations. Here is an example:
4x > x - 9
Subtract "x" on both sides:
3x > -9
Divide by 3:
x > -3
The main precaution is that if you multiply by a negative number, you MUST invert the inequality! Here is another example:
3x > 5x + 10
Subtract "5x" on both sides:
-2x > 10
Divide by (-2); note that the inequality MUST be turned around in this case:
x < -5

How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
How do you solve variables on both sides equation using integer rules?
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
How do you solve an equation with the same variable on both sides?
The variables may have different values.
How do you solve inequalities using addition subtraction multiplication and division.?
In the same wasy as you solve equations except that if you multiply or divide both sides by a negative number, then the inequality changes direction.
How do you solve inequalities by adding and subtracting?
Lets just say that the inequality is 3x+7 ≤ 13 so then you subtract 7 from both sides so that one side only has variables 3x ≤ 6 then divide each side by 3 to get x... x ≤ 2 c:
How can you use proportions to solve equations with variables on both sides?
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
How do you solve radical equations with variables on both sides?
First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
How do you solve inequalities with division?
e.g. 50>5x Divide both sides by five. 10>x
How do you solve variables on both sides equation using integer rules?
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.
How do you solve variables on both sides-negative coefficients?
-85-6x=91+2x
How do you solve an equation with the same variable on both sides?
The variables may have different values.
How do you solve an equation with two different variables on one side?
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
Are their similar things about inequalities and equations?
They both have variables.
Z-3 greater or equal to 25 solve inequality?
In simple cases such as these, you can solve inequalities just like an equation. In this case, you add 3 to both sides.
How do you solve inequalities using addition subtraction multiplication and division.?
In the same wasy as you solve equations except that if you multiply or divide both sides by a negative number, then the inequality changes direction.
How do you solve inequalities by adding and subtracting?
Lets just say that the inequality is 3x+7 ≤ 13 so then you subtract 7 from both sides so that one side only has variables 3x ≤ 6 then divide each side by 3 to get x... x ≤ 2 c:
How are the rules for solving inequalities similar to those for solving equations?
Solving inequalities and equations are the same because both have variables in the equation.
