Solving Equations Review

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.

What operation would you perform first and then second when solving for m in the following equation?

10 + 7m = 17

• subtract 10, then divide by 7

• divide by 7, then subtract 10

• multiply by 7, then add 10

• add 10, then multiply by 7

Solve for m:

10 + 7m = 17

• m=1

• m=-7.5

• m=129

• m=189

The steps in solving 5b - 6 = 24 are:

• Subtract 6 from both sides then divide both sides by 5

• Add 6 to both sides then multiply both sides by 5

• Subtract 6 from both sides then multiply both sides by 5

• Add 6 to both sides then divide both sides by 5

Solve for b:

5b - 6 = 24

• b=3.6

• b=150

• b=90

• b=6

Solve for a:

-3a + 8 = 14

• a = -2

• a = -7.5

• a = 2

• a = 6

Solve for x:

2x - 3 = 1

• x = 3

• x = 2

• x = 1

• x = -2

Solve for x:

2x - 3 + 4x = 27

• x = 12

• x = 4

• x = 5

• x = 15

Solve for b:
 3(b - 4) = -3

• b = 3
• b = -3
• b = 5
• b = -5

Solve for x:

7(2x - 4) = 42

• x = 5

• x = 8

• x = 2

• x = 9
