8xy + 7y + 2 = 12 ; x = -3 solve for y
First solve the equation for y, then find the value of y for the given value of x.
 
Solve the equation for y
 
8xy + 7y + 2 = 12 
8xy + 7y       = 12-2
8xy + 7y       = 10
y(8x + 7)      = 10
               y   = 10/(8x+7)
 
Find the value of y for the given value of x.
              y = 10/(8x+7)
               y = 10/ (8(-3) +7)
               y = 10/ (-24+7)
               y =  10/-17
               y = - (10/17)
