Solve the equation for y. Then find the value of y for the given value of x.
y - 2xy = 15;
Factor out y on the left side
y(1 - 2x) = 15
divide both sides by (1-2x)
y = {{{15/((1-2x))}}}
:
Then find the value of y for the given value of x. x = -1
y = {{{15/(1-2(-1))}}} = {{{15/(1+2)}}} = {{{15/3}}}
y = 5
:
:
Check this out, y - 2xy = 15
 replace x with -1, and y with 5
5 - 2(-2*5)= 15
5 -2(-10) = 15
5 + 10 = 15, confirms our solution of y=5
