Translating One-Step Equations

Correctly translated, 9 subtracted from a number is 12 would be...

• 9 - x = 12

• x - 9 = 12

• 9 + x = 12

• -9 + x = 12

Breanna went to the mall and spent $35.00 on shoes. When she she got home she had $40.00 in her purse. Which equation can be used to find the amount of money she started with?

• 35.00 + x = 40.00

• 40.00 - 35.00 = x

• 35.00x = 40.00

• 40.00x = 35.00

Last Friday Cicely had $22.50. Over the weekend she received some money for cleaning out the attic. She now has $32. Which equation represents how much money she received?

• 22.50/ x = 32

• 32/ 22.50 = x

• 22.50 + x = 32

• 32 - x = 22.50

Girl scouts make about $0.70 per box of cookies sold. If they need to earn $595 for a new tent for their camping trip, which equation can be used to determine how many boxes they would need to sell? Solve the equation

• 595+ x = 0.70; x = 595.70

• x/0.70 = 595; x =416.5

• 0.70x = 595; x = 850 

• 595 - x = 0.70; x = 594.30

Solve for x.

• 15

• 35

Solve for x

• x = 2

• x = -2

• x = -10

• x = 4

Solve the following one-step equation
r - 18 = 27

• r= 45

• r= 42

• r= 54

• r= 24

Solve the following equation
j + 17 = 19 

• j= 2

• j= 36

• j= 24

• j= 6

eight more than a number is twenty

• 8 + x = 20

• x + 20 = 8 

• x- 20 = 8 

• 8 - x = 20 

one-fourth of a number is 12 

• 1/4x = 12

• 14x = 12

• x14 = 12

• x1/4 = 12
