• 23

• -7

• 7

• -23

3 = c -1

• 3

• 4

• -3

• 2

What equation matches this situation?
Robyn had some video games then bought 4 more.  Now she has a total of 10 games.

• v - 4 = 10

• v + 4 = 10

• 10 - 4 = v

• Answer not Given

5 less than a number is 15.

• x - 5 = 15

• 5 - x = 15

• 15 - x = 5

What is the sum of 14 and x?

• x - 14

• 14(x)

• 14 + x

• 14/x

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.

What would be the best first step to solving the equation in one step?

• multiply both sides by 11

• multiply both sides by ¹/₂

• divide both sides by 2

• multiply both sides by 2

Which equation has x = 5 as the solution?

• x + 15 = 10

• 2x = 5

• 2x = 10
