Equations

w/5 = -10

• w = -50
• w = 50
• w = 2
• w = -2

z/-7 = -7

• z = 1
• z = -1
• z = 49
• z = -49

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.

6z + 3 -4z = 9

• z = 3
• z = 60
• z = 30
• z = 1

11b+7=40

• 2
• 1
• 4
• 3

Solve for x:
52 = -5x - 3

• x = 11
• x = -11
• x = 275
• x = -275

4 = 2(x + 3)

• 1/2
• 7/2
• -1
• 5

Solve: 5x - 14 = 8x + 4

• 6
• -6
• -18/13
• 10/3
