Solving Multi-Step Equations

I can solve multi-step equations with one variable.

Steps:

Write the original equation. 5=5m-23+2m

Gather like terms. 5=5m+2m-23

Combine the like terms. 5=7m-23

Add 23 to each side. 5+23=7m-23+23

simplify. 28=7m

Divide each side by 7

Simplify. 4=m

4=m

5=5(4)-23+2(4)

5=5

 $-8x\left(2x-1\right)=36$  

When solving an equation, the goal is to isolate the variable. Use the distributive property and combine like terms until a multi-step equation becomes a two-step equation.

Three friends go bowling. The cost per person per game is $5.30. The cost to rent shoes is $2.50 per person. Their total cost is $55.20. How many games did they play?
