on linear equations what do you do when the variables are diffrent like3x=5y?i got 3x+3x=5y+3x which equals??? thanks for the help austin

What you do depends on what you were asked to do. Are you solving it, graphing it, or what?
 
It is uncommon to be given a single linear equation in two variables. More often, you will be given a system of equations in more than one variable and asked to solve the system. Is that what you're having trouble with, by any chance?

if you're given 3x = 5y, then you have 3x - 5y = 0

you (normally!) would be given a 2nd similar equation, like 2x + 3y = 24

you would then solve for x and y using the 2 equations

BUT, if you're ONLY given 3x = 5y, then not much can be done:
x = 5y / 3 or y = 3x / 5

...and are you telling us your teacher "suddenly" sprang equations
with 2 unknowns on you, without any explanation 8-)
