Solve Problems with One Step Equations

x - 4 = 17

• x = 21

• x = 13

• x = 19

• x = 24

x + 24 = 44

• x = -20

• x = 68

• x = 20

• x = -68

To solve the equation
x + 5 = 8
 I would ....

• subtract 5 from x

• subtract 5 from both sides

• subtract 5 from one side and add 5 to the other

• add 5 to both sides

Solve the equation
3x = 27. 

• x = 24

• x = 81

• x = 9

c - 11 = 9

• c = -2

• c = -20

• c= 2

• c = 20

r/4 = 13

• r = 17

• r = 52

• r = 27

• r = 9

c/16 = 2

• c = 1

• c = 2

• c = 32

• c = 18

in 3a =12,
I would....

• add 3 to both sides

• subtract 3 from both sides

• divide both sides by 3

• divide just the right by 3

a ÷ 5 = 30

• a = 6

• a = 30

• can't be solved

• a = 150
