Answer:
-12
Step-by-step explanation:
2n - 6 = -30
Add both 6 on each side
2n - 6 + 6 = -30 + 6
2n = -24
Divide 2 on both sides
![\frac{2n}{2} = \frac{-24}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2n%7D%7B2%7D%20%3D%20%5Cfrac%7B-24%7D%7B2%7D)
n = -12
The equation of the line is y = -2x + 4
20+20=40
40 x 12 = 480
480 divded by 10 = 48$
it would be $48
