What is the solution to -2|2.2x-3.3|=-6.6? x=-3 x=3 x=-3 or x=0 x=0 or x=3

Divide by -2.2.

... |2.2x -3.3| = 3.3

Resolve to two equations:

... -3.3 = 2.2x -3.3 . . . . . . when the argument of the absolute value is negative

... 0 = 2.2x . . . . add 3.3

... 0 = x . . . . . . . divide by 2.2

... 2.2x -3.3 = 3.3 . . . . . . when the argument of the absolute value is positive

... 2.2x = 6.6 . . . . add 3.3

... x = 3 . . . . . . . . . divide by 2.2

The appropriate choice is ...

... x=0 or x=3 . . . . corresponds to the last selection
