Solving 1 Step Equations

17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19

4x = 44

• x = 40
• x = 11
• x = 48
• x = 176

2 + n =16

• 18

• -18

• 14

• -14

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9
• x = 3

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations
• math
• variable
• PEMDAS

c - 11 = 9

• c = -2
• c = -20
• c= 2
• c = 20

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

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

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
