Question

What is the solution set for |–2x + 8| = 12
Answer

x = –2 and x = 10

x = 2 and x = –10

x = –2 and x = –10

x = 2 and x = 10

Answer 1

x=-2 and x=10

Answer 2

1

Answer 3

|–2x + 8| = 12

–2x + 8 = 12
8 - 12 = 2x
-> x = -4/2 = -2

–2x + 8 = -12
8 + 12 = 2x
-> x = 20/2 = 10
Thus x = -2, x =10
