Solving two-step equations
Introduction
To solve an equation containing a variable, you must find the value of the variable that makes the equation true. The value is a solution of the equation. To find the solution, you can use the properties of equality to form equivalent equations, which are equations that have the same solution.
In order to solve any equation we must get the variable alone on one side of the equals sign. This is done by using the inverse operation, which are the operations that undo one another. "addition and subtraction are inverse operation, and division and multiplication are inverse operations"
An equation is like a balance scale because it shows that two quantities are equal.
