Solving Algebra Equations with Addition and Subtraction
One of the basic concepts of algebra is the equation. The main thing to know about an equation is that everything on one side of the equal sign (=) must equal everything on the other side of the equal sign. Variables are things that can change or have different values. In algebra, we are usually trying to find the value of one or more variables. In algebraic equations, the variable is represented by a letter.
Things to Remember:
1. Always perform the same operation to both sides of the equation.
2. You can add and subtract numbers from both sides of the equation to solve for x or y.
3. Always double check you answer by plugging it back into the original equation.
