The answer is 31 why? you replace the variable with -3
So it's f (a)=-2 (-3)(2)-5 (-3)+4
f (a)=31 that is the final answer.

How do you show your work on this question -x/3+2=-5
Ilya [14]

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
