Solving 1-Step Equations

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

• Inverse operations
• math
• variable
• PEMDAS

Solve for x
17 = x + 3

• x = 20
• x = 14
• x = 13
• x = 19

x - 4 = 17

• x = 21
• x = 13
• x = 19
• x = 24

x - 18 = 3

• x = 37
• x = 15
• x = -21
• x = 21

x + 24 = 44

• x = -20
• x = 68
• x = 20
• x = -68

19  + a  =  -50

• a = -950
• a =  -69
• a = -31
• a = -50/19

c - 11 = 9

• c = -2
• c = -20
• c= 2
• c = 20

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

r/4 = 13

• r = 17
• r = 52
• r = 27
• r = 9
