One-Step Equations Vocabulary

Solve for x:

• x = 20

• x = 7

• x = 10

• x = 3

What is the correct step to solve for the variable?
15 = m - 5

• add 15 to both sides

• add 5 to both sides

• subtract 15 from both sides

• subtract 5 from both sides

x + 40 = 56

• x = 16

• x = 96

• x = 15

• x = 10

y + 51 = 99

• 140

• 150

• 48

• Answer not Given

12 + z = 15

• -3

• 3

• -27

• 27

a + 4 = 14

• -10

• 10

• -18

• 18

r + 20 = 27

• r = 7

• r = 47

• r = 13

• r = 20

6x = 30

• x = 5

• x = 24

• x = 6

• x = 36
