Solution for 7/8y+1/7(y-8)=(y+1)/4 equation: 


y in (-oo:+oo)

(1/7)*(y-8)+(7/8)*y = (y+1)/4 // - (y+1)/4

(1/7)*(y-8)-((y+1)/4)+(7/8)*y = 0

1/7*(y-8)+(-1*(y+1))/4+(7*y)/8 = 0

(1/7*4*8*(y-8))/(4*8)+(-1*8*(y+1))/(4*8)+(4*7*y)/(4*8) = 0

1/7*4*8*(y-8)-1*8*(y+1)+4*7*y = 0

28*y-24/7*y-312/7 = 0

172/7*y-312/7 = 0

(172/7*y-312/7)/(4*8) = 0

(172/7*y-312/7)/(4*8) = 0 // * 4*8

172/7*y-312/7 = 0

172/7*y-312/7 = 0 // + 312/7

172/7*y = 312/7 // : 172/7

y = 312/7/172/7

y = 78/43

y = 78/43
