What is the solution to - 2|2.2x - 3.3| = - 6.6?

a. x = - 3

b. x = 3

c. x = - 3 or x = 0

d. x = 0 or x = 3

Hello,

Answer D

1) if 2.2x-3.3>0 then |2.2x-3.3|=2.2x-3.3

==>-2 (2.2x-3.3) = - 6.6

==>-4.4x=-6.6-6.6

==>x=3

2)

if 2.2x-3.3<0 then |2.2x-3.3| = - (2.2x-3.3)

==>-2 (-2.2x+3.3) = - 6.6

==>4.4x=-6.6+6.6

==>x=0
