Math Problem Statement

Solve for x in the equation 5 = |2x - 3|

Solution

The equation given is:

5=2x35 = |2x - 3|

To solve this, we need to remove the absolute value, which leads to two cases:

Case 1: 2x3=52x - 3 = 5

Solve for xx: 2x3=52x - 3 = 5 Add 3 to both sides: 2x=82x = 8 Divide by 2: x=4x = 4

Case 2: 2x3=52x - 3 = -5

Solve for xx: 2x3=52x - 3 = -5 Add 3 to both sides: 2x=22x = -2 Divide by 2: x=1x = -1

Thus, the solutions are x=4x = 4 and x=1x = -1.

Looking at the choices, the closest match is the option where x=1,4x = -1, 4, which seems to correspond to the correct solution.
