Sample questions

1. What is the solution to the equation 2x + 3 = 7?

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

   Answer: B. x = 2

   To solve 2x + 3 = 7, subtract 3 from both sides to get 2x = 4. Then divide by 2 to find x = 2.

2. What is the value of y if 2y + 6 = 10?

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

   Answer: B. y = 2

   Subtract 6 from both sides to get 2y = 4. Divide by 2 to find y = 2.

3. For the equation 6x - 2 = 10, what is x?

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

   Answer: A. x = 2

   Add 2 to both sides to get 6x = 12. Then divide by 6 to find x = 2.

4. For which x is 3x + 4 = 19?

   1. x = 4
   2. x = 5
   3. x = 6
   4. x = 7
   Show answer

   Answer: B. x = 5

   Subtract 4 from both sides to get 3x = 15. Divide by 3 to find x = 5.

5. What is y if 5(y - 2) = 15?

   1. y = 3
   2. y = 4
   3. y = 5
   4. y = 6
   Show answer

   Answer: C. y = 5

   Divide both sides by 5 to get y - 2 = 3. Add 2 to find y = 5.
