Answer:
[tex]x = -11[/tex]
Step-by-step explanation:
We have: [tex]-3(x + 2) = 16 -x[/tex]
In order to prove or disprove this we will solve for x.
[tex]-3(x + 2) = 16 -x[/tex]
[tex]-3x + (-2)*3 = 16 -x[/tex]
[tex]-3x - 6 = 16 -x[/tex]
[tex]-3x - 6+6 = 16 -x+6[/tex]
[tex]-3x = 22-x[/tex]
Then we have to get x on one side so we do:
[tex]-3x + x = 22 -x + x[/tex]
[tex]-2x = 22[/tex]
Solve for x by dividing by [tex]-2[/tex].
[tex]\frac{-2x}{-2}=\frac{22}{-2}[/tex]
[tex]x = -11[/tex]
