Math Problem Statement

Solve the equation |2x - 6| = 8. Choose the 2 correct answers.

Solution

We are given the equation 2x6=8\lvert 2x - 6 \rvert = 8.

To solve this equation, we need to break it down into two cases because of the absolute value:

Case 1: 2x6=82x - 6 = 8

Solve for xx: 2x6=82x - 6 = 8 Add 6 to both sides: 2x=142x = 14 Divide by 2: x=7x = 7

Case 2: 2x6=82x - 6 = -8

Solve for xx: 2x6=82x - 6 = -8 Add 6 to both sides: 2x=22x = -2 Divide by 2: x=1x = -1

Thus, the two solutions are x=7x = 7 and x=1x = -1.

The correct answers are 77 and 1-1.
