Review One Step Equation

g - 16 = 4

Solve for the variable.
x - 5 = 20

• x = -25

• x = -15

• x = 15

• x = 25

r + 20 = 27

• r = 7

• r = 47

• r = 13

• r = 20

Solve for x.

Write an equation to represent the problem given: After paying $5.12 for a salad, Nora has $27.10. How much money did she have before buying the salad?

• n + $5.12 = $27.10

• n - $5.12 = $27.10

• $5.12 - n = $27.10

Solve the word problem.
After paying $5.12 for a salad, Nora has $27.10. How much money did she have before buying the salad?
Use the equation:
n−5.12=27.10

• $32.22

• $22.02

• $21.98
