Distribute:
-7(w + -2)

• -7w + 14
• -7w + -14
• -7w + -9
• -5w

Solve the equation:
8y = 24

• y = 4
• y = -3
• y = 16
• y = 3

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Simplify the expression:

2a - 3b - 5a + 10 - 3b

• -3a + 10

• -3a - 6b + 10

• -9ab + 10

• 7a - 6b - 10

Solve for x:

x + 10 = 24

• x = 14

• x = 4

• x = 34

• x = -14

Solve for x.

-2x + 6 = -12

• x = 9

• x = -8

• x = -16

• x = 3
