we have

$-2\left|2.2x-3.3\right|=-6.6$

Step 1

Find the first solution

the first solution is when the term contained in the absolute value is positive

-2[(2.2x-3.3)]=-6.6

solve for x

$-4.4x+6.6=-6.6\\-4.4x=-6.6-6.6 \\ -4.4x=-13.2\\x=3$

Step 2

Find the second solution

the second solution is when the term contained in the absolute value is negative

-2[-(2.2x-3.3)]=-6.6

solve for x

$4.4x-6.6=-6.6\\ 4.4x=0\\x=0$

therefore

the answer is
