Cheryl gets paid $8 per hour for her job at the record store and $15 for working late on Saturday. She made a total of $96 last week. Which equation models this situation?

• 96h + 15 = 8

• h/96 = 8

• 8h + 15 = 96

• 8h = 96

What is the "2nd step" to solve this equation?
3x - 5 = 7

• Add 5 to both sides of the equation

• Divide -3 on both sides of the equation

• Subtract 5 to both sides of the equation

• Divide 3 on both sides of the equation

5 - 2x = x + 8

What is the first step to solving variables on both sides of the equation?

• move -2x to the opposite side by using inverse operation

• multiply by 5 on both sides

• add 8 on both sides

• x = - 3
