Sample questions

1. Solve for x: 2x + 5 = 11

   1. x = 3
   2. x = 8
   3. x = 6
   4. x = 16
   Show answer

   Answer: A. x = 3

   Subtract 5 from both sides: 2x = 6. Then divide both sides by 2: x = 3

2. Solve for a: 5a + 12 = 27

   1. a = 3
   2. a = 7
   3. a = 5
   4. a = 15
   Show answer

   Answer: A. a = 3

   Subtract 12 from both sides: 5a = 15. Then divide both sides by 5: a = 3

3. Solve for y: 3(y - 2) = 18

   1. y = 8
   2. y = 6
   3. y = 10
   4. y = 7
   Show answer

   Answer: A. y = 8

   Distribute the 3: 3y - 6 = 18. Add 6 to both sides: 3y = 24. Divide by 3: y = 8

4. Solve for n: 2/3n - 5 = 1

   1. n = 9
   2. n = 6
   3. n = 18/2
   4. n = 3
   Show answer

   Answer: A. n = 9

   Add 5 to both sides: 2/3n = 6. Multiply both sides by 3/2: n = 9

5. Solve for x: (x+2)/3 + 1 = 5

   1. x = 4
   2. x = 10
   3. x = 6
   4. x = 8
   Show answer

   Answer: B. x = 10

   Subtract 1 from both sides: (x+2)/3 = 4. Multiply both sides by 3: x+2 = 12. Subtract 2 from both sides: x = 10
