Solve Two-Step Equations P(X+Q)=R

Did Sarah make an error? If so, which is the best description of her error?

• She didn't distribute correctly. The second step should read 3x - 12 = 24

• She didn't distribute correctly. The second step should read -3x - 12 = 24

• She didn't distribute correctly. The second step should read -3x + 12 = 24

• She didn't make an error.

Solve for x.

2(x + 15) = -6

• x = -10.5

• x = -18

• x = 18

• x = 10.5

Solve for y.

• y = -5.6

• y = 5.6

• y = -8.75

• y = 8.75

Solve for w

5w - 7 = 23

• x=3

• x=-7

• x=0

• No Solution

• 2

• -2

• 8

• 8

What is the value of t that satisfies the equation?

• 10
  

• 11

• x=3

• x=2

• x=-2

• x=1
