Equations Practice

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Select the following basic rules used for solving one step equations?

• Whatever you do to one side of the equal sign, you must copy and do on the other side of the equal sign

• Negative signs can be ignored

• Always start on the left side, regardless of where the variable is

• Always do the inverse operation

• Divide both sides by 11

• Multiply both sides by 11

• Add 11 to both sides

• Subtract 11 to both sides
