Question

I dont know how to do this at all and need alot of help
3x-5y=9
it wants to know the equation for y and the value for y and x

Answer 1

I would start by adding 5y to both sides.

You can perform most operations on an equation without changing it, as long as whatever operation you perform is done on both sides of the equation.

Answer 2

the only way you can solve for a value of y or x is to have a second equation. but you can make two equations from the one equation given and have one be x= and the other be y=
