Solve One Step Equations with Addition and Subtraction

S + 18 = 24

• S = 42

• S = 3²

• S = 18

• S = 4 + 2 

What equation matches this situation?

Jack had some markers and then bought 6 more. Now he has a total of 10 markers.

• m - 6 = 10

• m + 6 = 10

• 10 - 6 = m

• Answer not Given

17 = x + 3

• x = 20

• x = 14

• x = 13

• x = 19

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 

• Subtract 62 from each side.

• Multiply each side by 62.

• Add 123 to each side.

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 + 3 = 11

• x=8

• x=14

• x=3

• x=33

y + 10 = 22

• y=12

• y=22

• y=2

• y=32

b - 4 = 9

• b=9

• b=36

• b=13

• b=5

x + 7 = 18

• x=25

• x=7

• x=18

• x=11

6 + z = 14

• z=20

• z=8

• z=6

• z=0
