Sample questions

1. What is the value of x in the equation 2x + 3 = 7?

   1. 1
   2. 2
   3. 3
   4. 4
   Show answer

   Answer: B. 2

   To find x, we subtract 3 from both sides: 2x = 7 - 3 = 4. Then divide by 2: x = 4 / 2 = 2.

2. If 3x + 7 = 16, what is the value of x?

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

   Answer: A. 3

   Subtract 7 from both sides: 3x = 16 - 7 = 9. Then divide by 3: x = 9 / 3 = 3.

3. What is the solution to x + 5 = 12?

   1. 1
   2. 5
   3. 7
   4. 17
   Show answer

   Answer: C. 7

   Subtract 5 from both sides: x = 12 - 5 = 7.

4. What is the solution to 5x + 2 = 17?

   1. 3
   2. 4
   3. 2
   4. 1
   Show answer

   Answer: A. 3

   Subtract 2 from both sides: 5x = 17 - 2 = 15. Then divide by 5: x = 15 / 5 = 3.

5. Find x if 3(x - 1) = 6.

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

   Answer: A. 3

   Divide both sides by 3: x - 1 = 6 / 3 = 2. Then add 1: x = 2 + 1 = 3.
