solve for y: ax+by=c
This is called a literal equation since there are no numbers.
To solve for y means to isolate y.
The same applies to any variable we are solving for.

ax + by = c
by = c - ax
y = (c - ax)/b
NOTE: y = (-ax + c)/b is the same thing as y = (c - ax)/b.
We can apply the commutative rule of addition on the numerator allowing us to switch the terms around not changing the value of the entire fraction. Understand?

Solve for y; ax+by=c
first subtract ax from both sides
ax+by=c
-ax -ax
we get by=c-ax; now divide by b, we get
by/b=c/b-ax/b; simplify
y=c/b-a/b*x answer.......I hope this helps!
