Answer:
x = 5
Step-by-step explanation:
4x = 7 - 8x - 27
1) Combine like terms (7 and -27). So, 7 + (-27) = -20.
4x = 8x - 20
2) Subtract 8x from both sides of the equation. So, 4x - 8x = -4x.
-4x = -20
3) Divide both sides by -4. So, -20 / -4 = 5.
x = 5
There are 20 1/5 parts in 4.
1/5*20 = 4
Mistake in line one
He forgot to factor the 2 out of -8x
