Solving One Step and Multi-Step Equations Review

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

Solve:
32 - 7x = -6(x + 3)

• 50

• 3

• -3

• -50

What is the first step in solving the following equation?

-3x + 5 = 20

• Subtract 5 from both sides

• Divide both sides by -3

• Divide both sides by 3

• add 3x to both sides

Solve m - n = 5 for m.

• m = 5 + n

• m = -5 - n

• m = -5 + n

• m = 5 - n

Solve:
8x + 4y = 16    ,  for     y

• y = -2x + 4

• y = 2x - 4

• y = 2x + 4

• y = -2x - 4

Solve for x. 
x + 7g = 9

• x = 9 - 7g

• x = 9 / 7g

• x = 9 + 7g

• x = 7g - 9

An equation has ____________ when you simplify and the variable terms on each side are the same, BUT the constants are different.

• one solution

• two solutions

• no solution

• infinite solutions

An equation has ____________ when you simplify and the variable terms on each side are the same, AND the constants are the same.

After moving the constant to one side in the following equation, what would be the result: 70x + 48 = -22

• 70x = 70

• 70x = -70

• 70x + 70 = 0

3x + 2(4x - 4) = 3

• 4

• 3

• 2

• 1
