Solving 1 step equations!

• You use the inverse operation, which undo each other to get the variable alone.

• Check your solution.

To Solve

• Subtract, multiply, add, or divide depending on the inverse operation.

• Check your solution• *Remember* Whatever you do to one side, you must

do to the other. EXAMPLE!- x+2=4 x=2

How to solve 2 step equations!

1. Divide your problem in half.

2. Circle the variable

3. Get rid of the number next to the variable by adding or subtracting.

4. Multiply or divide and check solution.

*EXAMPLE* 2x+7=-15 x= -11

Always think of a balance when solving equations.
