8xy + 7y + 2 = 12 ; x = -3 solve for y

Question

First solve the equation for y Then find the value of y for the given value of x.

Answer 1

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)
