Answer:

The solutions to the equation are x = 6 and x = 8

Explanations:

The given equation is:

4|2x - 14| + 10 = 18

Note:

|2x - 14| is an aboslute expression which can either be (2x - 14) or -(2x - 14)

Therefore, the equation has two solutions:

The first solution:

4 ( 2x - 14) + 10 = 18

4 ( 2x - 14) = 18 - 10

4 (2x - 14) = 8

2x - 14 = 8 / 4

2x - 14 = 2

2x = 2 + 14

2x = 16

x = 16 / 2

x = 8

The second solution

-4(2x - 14) + 10 = 18

-4 ( 2x - 14) = 18 - 10

-4 ( 2x - 14) = 8

2x - 14 = -8 / 4

2x - 14 = -2

2x = -2 + 14

2x = 12

x = 12 / 2

x = 6

The solutions to the equation are x = 6 and x = 8
