we have
[tex]-2\left|2.2x-3.3\right|=-6.6[/tex]
Step 1
Find the first solution
the first solution is when the term contained in the absolute value is positive
[tex]-2[(2.2x-3.3)]=-6.6[/tex]
solve for x
[tex]-4.4x+6.6=-6.6\\-4.4x=-6.6-6.6 \\ -4.4x=-13.2\\x=3[/tex]
Step 2
Find the second solution
the second solution is when the term contained in the absolute value is negative
[tex]-2[-(2.2x-3.3)]=-6.6[/tex]
solve for x
[tex]4.4x-6.6=-6.6\\ 4.4x=0\\x=0[/tex]
therefore
the answer is
[tex]x = 0[/tex] or [tex]x = 3[/tex]
