Question 248476
Solve proportional equation 
x= 7y + 2
_______
y-3 
Solve for y 

x = (7y+2)/(y-3)

Multiply both sides by y-3:
x*(y-3) = 7y+2

Expand:
xy-3x = 7y+2

Subtract 7y from both sides and add 3x to both sides:
xy-7y = 3x+2

Factor out y from both terms on the left:
y(x-7) = 3x+2

Divide both sides by x-7
y = (3x+2)/(x-7)
