y = 28 / 3
-48=-5y+8-y
First make y positive by * -1.
48 = 5y - 8 + y
5y + y - 8 = 48
6y - 8 = 48
ax = b formula - Take the - 8 to the other side.
6y - 8 + 8 = 48 + 8
6y = 56
x = b formula
Divide by 6:
6y / 6 = 56 / 6
y = 28 / 3
Check the answer by substituting it into the original equation:
-48 =-59 (28 / 3) + 8 - (28 / 3)
