19  + a  =  -50

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

144=12z

• z=20
• z=11
• z=12

w/11 = 8

• w = 3
• w = -3

• w = -88

y - 4.6 = 12

• 16.6
• 5.8
• 7.4
• Answer not Given

Which equation has x = 5 as the solution?

• x + 15 = 10
• 2x = 5
• 2x = 10

In the equation
x + 7 = 12
7 is being added to the variable, x. How should you show your work to isolate the variable and solve the equation? 

• Subtract 7 from both sides. The solution is x = 5.
• Add 7 to both sides.
  The solution is x = 19.
• Multiply both sides by 7 The solution is x = 84.
