Lesson 8: Solving 2-Step Equations

Show the steps to solve for x.

4x + 5 = 13

• x = 4

• x = 2

• x = 13

• x = 5

Show your steps to solve for x.

2(x+3) =4

• x = 2

• x = -1

• x= 1

• x=0

4x - 7 = 21

• x = 12

• x = 7

• x = 24

Show your steps to solve for x.

3(3 + x) = 21

• x = -2

• x = 3

• x = 4

• x = 5

What is the first step to solve this equation:

-3x + 11 = 44

• Add 3 to both sides

• Subtract 11 from both sides

• Add 11 to both sides

• Divide 3 on both sides.

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

2k + 12 = -4

• -8
• 8
• -10
• 4

What is the first step in solving this equation 8x - 6 = 10

• Add 6

• Subtract 8

• Divide by 8

• Subtract 6

3x + 2 = -25

• x = -8
• x = -9
• x = 9
• x = 24
