What is the inverse operation you would use to solve:
6x = 36

• Multiply
• Divide
• Add
• Subtract

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5

19  + a  =  -70

• a = -1330
• a =  -89
• a = -51
• a = -70/19

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Solve the equation below:

• k = 152
• k = 176
• k = 5
• k = 27

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.

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

x/5 - 13 = 20

• 145
• 165
• 180
• 190

15 = 2a + 7

• 2
• 4
• 12
• 14

- 5 + x/12 = -6

• -12
• -19
• 11
• 15
