Question

Choose the two equations you would use to solve the absolute value equation below. Then solve the two equations. |2x + 5| = 3 A. 2x + 5 = 3 and 2x + 5 = –3; {–1, –4} B. 2x + 5 = 3 and 2x + 5 = –3; {1, –4} C. 2x – 5 = 3 and 2x + 5 = –3; {–1, 4} D. 2x – 5 = 3 and 2x + 5 = –3; {–1, –4}

Answer 1

To solve

|2x + 5| = 3

solve these 2 equations

2x + 5 = 3 and 2x + 5 = -3

Solution:

2x + 5 = 3 or 2x + 5 = -3

2x = -2 or 2x = -8

x = -1 or x = -4

The correct answer is choice A.
