Solution

Answer Key

1)  x = 17 (or) x = -7

2)  x = -2 (or) x = -14

3)  a = 6 (or) a = -1

4)  b = 7 (or) b = -3

5)  x = 7 (or) x = 1

6)  y = 3 (or) y = -4

7)  x = 5 (or) x = 9

8)  a = -3 (or) a = 3

9)  b = 2 (or) b = -10

10)  x = 8 (or) x = -3

11)  there is no solution.

12)  x = -3 (or) x = 17

Solve each equation. Check for extraneous solution.

1)  |3x – 4| = x              Solution

2)  |x + 24| = -7x         Solution

3)  |8x – 1| = 6x               Solution

4)  |4x + 5| = 2x + 4        Solution

5)  |9 – 2x| = 10 + 3x           Solution

6)  |8 + 5x| = 7 - x           Solution

7)  |x – 1| = 5x + 10         Solution

8)  |2z – 3| = 4z - 1          Solution

9)  |3x + 5| = 5x + 2           Solution

10)  |2y – 4| = 12           Solution

11)  3|4w – 1| - 5 = 10           Solution

12)  |2x + 5| = 3x + 4          Solution

Answer Key

1) x = 2 and x = 1, No extraneous solution

2)  x = -3 and x = 4, 4 is extraneous solution

3)  x = 1/2 and x = 1/14, no extraneous solution.

4)  x = -1/2 and x = -3/2, no extraneous solution.

5)  x = -1/5 and x = -19, -19 is extraneous solution.

6)  x = -1/6 and x = -15/4, no extraneous solution.

7) So, -3/2 is a solution and -11/4 is an extraneous solution.

8) So, -1 is a extraneous solution

9)  So, -7/8 is the extraneous solution.

10)  So, there is no extraneous solution.

11)  So, there is no extraneous solution.

12)  So, -9/5 is a extraneous solution.
