Question 1126331: Hi!
I have a linear equation question that says to solve for y. When I did the problem I got y=(ba-bx)/a but I'm not sure that is correct. the equation says:
(x/a)+(y/b)=1
Thank you,

Try to isolate any terms of y on one side.

y%2Fb=1-x%2Fa


Multiply both sides by b.

b%28y%2Fb%29=b%281-x%2Fa%29

y=b-bx%2Fa and you can use fraction arithmetic to make the right side as one single expression, if you want it that way, which you did already, correctly.

x/a + y/b = 1 multiply both sides times a and b
ab(x/a) + ab(y/b) = 1
on the left a cancels a and on the right b cancels b, and you get:
bx + ay = 1

IGNORE what the other people are saying. You need to know if you're correct and I will say that you are. Good job!!

The answer that you have: matrix%281%2C3%2C+y%2C+%22=%22%2C+%28ba+-+bx%29%2Fa%29 can also be written as:
