Solving Two- Step Equations

What is the first step you would make to solve this equation ?

2x-14 = 34

• Add 14 to both sides

• Subtract 14 to both sides

• Combine Like Terms

• Divide both sides by 14

Solve the following equation

2x-14 = 34

• x = 10

• x = 24

• x = 17

• x = 22

To solve a simple two-step equation you need to...

• 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 to isolate the variable

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

• Multiply by zero first to isolate the variable

Solve the equation

5x+3 = 28

• x = 5

• x= 3.8

• x = -5

• x = 10

What is the value for "m" that makes the equation true?

11m - 10 = 56

• m = 10

• m = 6

• m = 66

• m = 11

Solve

15 = 2a + 7

• a = 2

• a = 12

• a = 4

• a = 14

Solve the following equation

2d +7 = 9

• d=0

• d= -2

• d = 1

• d= 8

4 (x +2) = 16

• x=2

• x=4

• x=7

• x=10
