Question

5) ||2x - 3| - X+1| = 4x − 1

Answer 1

X= -2x - 1,2x + 3

Explanation:

1)Break down the problem into these 2 equations.

(2x-3) - X+ 1 = 4x − 1

-(-(2x-3) - X + 1) = 4x − 1

2)Solve the 1st equation: (2x-3) - X + 1 = 4x − 1.

X=-2x 1

3)Solve the 2nd equation: -(-(2x-3) − X + 1) = 4x – 1.

X = 2x + 3

4)Collect all solutions.

X= -2x - 1,2x + 3
