Two Step Equation Review

Identify the steps to solve for b

• 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

To Solve a Simple Two-Step Equation you need to ...

• Undo the Addition/Subtraction first (to remove the constant term), then undo the Multiplication /Division (to remove the coefficient and isolate the variable)

• Undo the Multiplication/Division first (to remove the coefficient and isolate the variable), then undo the Addition/Subtraction (to remove the constant term)

• Multiply both sides by 1

• Substitue zero for the variable (to remove the variable and isolate the constant

-6x = 30

• x = - 5

• x = 24

• x = 5

• x = 36

Solve the following equation

2y = 18

• y = 36

• y = 16

• y = 9

• y = 20

Solve for w:
-6w + 1 = -11

• 2

• 1.2

• 12

• -2

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8

Which value of w makes the following equation true?

w + (-6) = 81

• -75

• 75

• 87

• -87

4x + 7 = 23

• x = 16

• x = 4

• x = 9

• x = 12

x - 8 = -5 

• 13

• -13

• 3

• -3

-4x+1=21

• x=120

• x=5

• x=30

• x=-5
