• no matter what constant is substituted in for the variable, the equation will NEVER be true

• only this ONE solution will make the equation true

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 x:

7(2x - 4) = 42

• x = 5

• x = 8

• x = 2

• x = 9

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.

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

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

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

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

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

Solve for x:

2x -1(3+4x) = 11

• x = -4

• x = 7/3

• x = -7

• x = -17/8
