How does writing equivalent equations help you solve a system of equations?
You can write an equivalent equation from a selected equation in the system of equations to isolate a variable. You can then take that variable and substitute it into the other equations. Then you will have a system of equations with one less equation and one less variable and it will be simpler to solve.
How are linear inequalitys differant from linear equations?
Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
Could the value of the variable be greater than 12.50?
The unknown value of the variable could be greater, less or even equal to 12.50
What is the difference between equality and inequality?
equality does not change signs inequalities do for greater than or less than equations
What is the Difference between solving equations and inequalities?
When solving an equation, you are looking for a specific answer or answers. However, when solving inequalities, you are only looking for what an answer could be (for example, your answer could be less than 5 or greater than 32).

How are linear inequalitys differant from linear equations?
Inequalities have greater than, less than, greater than or equal to, or less than or equal to signs. Equations have an equal sign.
When using the substitution to solve nonlinear system of equations you should first see if you can one variable if you can one variable in one of the equation in the system?
The general idea is to solve one of the equations for one variable - in terms of the other variable or variables. Then you can substitute the entire expression into another equation or other equations; as a result, if it works you should end up having one less equation, with one less variable.
How are equations and inequalities different?
Equations have and can only have a = Inequalities have <, >, greater than or equal to, less than or equal to, or =
Could the value of the variable be greater than 12.50?
The unknown value of the variable could be greater, less or even equal to 12.50
What are three forms of equations?
1. < less than 2. > greater than 3. = equal to
What is the difference between equality and inequality?
equality does not change signs inequalities do for greater than or less than equations
What is a linear equation in two variable?
An example is x+y=3 and 2y+x=5 these are more or less known as simultaenous equations
What is the Difference between solving equations and inequalities?
When solving an equation, you are looking for a specific answer or answers. However, when solving inequalities, you are only looking for what an answer could be (for example, your answer could be less than 5 or greater than 32).
What operation gives the solution to the inequality 4x 12?
An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal". Assuming one of these inequality signs is between the "4x" and the "12", for example: 4x < 12, just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.
What is the solution of an inequality?
solution is another name for answer It is the answer to an equation that looks like: 2x>-4 You have to find out what the "x" variable is For 2x > -4 (2 times x is greater than negative 4) you have to get "x" alone to find out what it is (or in other words, to find the solution) so you divide the 2 from the 2x and divide -4 by 2, turning the inequality (equation) into x > -5 -x being the variable, that means the answer is any number greater than -2 so x> -2 thats a good answer but here is mine: the answer to a problem using less than, less than or equal to, greater than, greater than or equal to, or equal.
Is 7 over 9 greater than or less than 2 over 4?
The answer is greater than, because 7 divided by 9 is .777777, and 2 divided by 4 is .5 .777 is greater than .5, and so 7/9ths is the greater of the two equations
