Carnegie Writing and Solving Equations

Translate: 5 less than a number, x, is 15.

• 5 - x = 15

• 15 - 5 = x

• x - 5 = 15

• 15 - x = 5

Translate: Two more than 4 times a number is 18.

• 4x + 2 = 18

• 18 = 4 + 2x

• 2x + 18 = 4

• 4x + 2 = 18

Translate into a word sentence: 3x - 8 = 34

• three times a number increased by 8 is 34

• the quotient of 3 and a number 8 equals 34

• eight less than three times a number is equal to 34

• three times a number fewer than 8 is the same as 34

Solve: 76 = x + 39

• x = 27

• x = 37

• x = 95

• x = 115

Solve the equation 2/3 x = 16

• x = 24

• x = 10

• x = 16

• x = 8

How do you solve this equation? 3x = 44

• add 3 to both sides

• subtract 3 from both sides

• multiply 3 on both sides

• divide 3 on both sides
