Hello!

[tex]\large\boxed{x = 21}[/tex]

[tex]\frac{-x}{3} + 2 = -5[/tex]

Begin isolating for x by subtracting 2 from both sides:

[tex]\frac{-x}{3} + 2 - 2 = -5 - 2\\\\\frac{-x}{3} = -7[/tex]

Further simplify by multiplying both sides by 3:

[tex]\frac{-x}{3} * 3= -7 * 3\\\\-x= -21[/tex]

Multiply both sides by -1 to cancel out the -x:

[tex]-x(-1) = -21(-1)\\\\x = 21[/tex]
