I didn't mention...

Is the solution an ordered pair or is there no solution

(4-3y) + 3y = 9

solve for y!

then plug the y value into

x=4-3y

solve for x!

you tell me. does y= a number? then, yes, it's an ordered pair

-3y and postive 3y cancel each other out, leaving 4 = 9, which is false.

So that means that there is not solution?
