Given:
.
2x-5y=8
.
Solve for y.
.
You can't get rid of the x term unless the problem specifically gives you a value for x.
.
The way you do this problem is to get just y on one side of the equation and everything
else on the other side.
.
Begin by getting rid of the 2x on the left side by subtracting 2x from both sides. Subtracting
2x from the left side cancels the existing 2x. On the right side you just insert -2x. So after
the subtraction of 2x from both sides the resulting equation is:
.
-5y = -2x + 8
.
Solve by y by dividing all three terms of this equation by -5 which is the multiplier
of y. This division converts the left side to just y. Each of the terms on the right side
are divided by -5 so that the equation is:
.

.
and this simplifies to:
.

.
That's the answer and is all you can do unless somebody gives you a value for x that you
can substitute into this equation.
.
Hope this helps you to understand the problem.
