Question

Solve the equation with the problem set {-28,-8,8,28} |10-x|=18

Answer 1

{-8,28}

Explanation:

|10-x|=18

The absolute value has two solutions, one positive and one negative.

10-x = 18 and 10-x = -18

Subtract 10 from each side

10-10-x = 18-10 10-10-x=-18-10

-x = 8 -x = -28

Multiply each side by -1

x = -8 x = 28
