Answer:

n = 35

Step-by-step explanation:

n - 13 x -2 = -44

distribute:

(n x -2) - (13 x -2) = -44

-2n - (-26) = -44

two negatives in front of a number makes it a positive number

so rewrite -2n + 26 = -44

-2n = -44 -26

-2n = -70

n = [tex]\frac{-70}{-2}[/tex]

n = 35

calc check (35 - 13) x -2 = 22 x (-2) = -44
