Sample questions

1. Solve the equation: 3x + 2 = 11

   1. x = 1
   2. x = 2
   3. x = 3
   4. x = 4
   Show answer

   Answer: C. x = 3

   To solve 3x + 2 = 11, subtract 2 from both sides to get 3x = 9, then divide by 3 to get x = 3.

2. What is x if 2x + 5 = 15?

   1. x = 2
   2. x = 5
   3. x = 10
   4. x = 15
   Show answer

   Answer: B. x = 5

   Subtract 5 from both sides to get 2x = 10, then divide by 2 to get x = 5.

3. Solve for x: 3(x + 4) = 21

   1. x = 1
   2. x = 2
   3. x = 3
   4. x = 4
   Show answer

   Answer: C. x = 3

   First, divide both sides by 3 to get x + 4 = 7. Then subtract 4 from both sides to find x = 3.

4. What is x if x/4 = 5?

   1. x = 10
   2. x = 15
   3. x = 20
   4. x = 25
   Show answer

   Answer: C. x = 20

   Multiply both sides by 4 to find x = 20.

5. What is the value of x if 3 - x = 2?

   1. x = 0
   2. x = 1
   3. x = 2
   4. x = 3
   Show answer

   Answer: B. x = 1

   Subtract 3 from both sides to get -x = -1. Multiply by -1 to find x = 1.
