Question

How do you show your work on this question -x/3+2=-5

Answer 1

Hello!

$\large\boxed{x = 21}$

$\frac{-x}{3} + 2 = -5$

Begin isolating for x by subtracting 2 from both sides:

$\frac{-x}{3} + 2 - 2 = -5 - 2\\\\\frac{-x}{3} = -7$

Further simplify by multiplying both sides by 3:

$\frac{-x}{3} * 3= -7 * 3\\\\-x= -21$

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

$-x(-1) = -21(-1)\\\\x = 21$
