+73 solve for y: xy-wy = t
I got an answer myself, im not sure if this is rite, its y= -(t/w-xy/w)
+590 Well, in xy-wy = t, you know that xy and wy both have y in them. (Yeah, that's not really a good explanation -_-)
So you can make that into: y(x-w) = t. Because if you distribute y to (x-w), the result is the same as the original.
Now, we have y(x-w) = t.
We need to isolate y to solve for y.
So divided both sides by (x-w) to isolate y.
you get y = t/(x-w)
And that's the answer.
Correct me if I am wrong.
