Math Lab #2 Equations Review

Solve the equation:
-5x = 25

• x = 20
• x = -20
• x = -5
• x = 5

19  + a  =  -50

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

5.    6b = 30

• x = 36
• x = 24
• x = 180
• x = 5

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

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.

x + 12 = 20

• x = 32
• x = -32
• x = 8
• x = -8

Solve the equation:
x - 5.5 = 10.5

• x = 16
• x = -15
• x = 5
• x = -5

x - (-1) = 11

• x = 10
• x = 12
• x = -10
• x = 11
