I can't do anything either with the information provided. Need more data.

divide both sides by 7 and you'll get x= -2y/7

P.s. PsyDAG, you already have all the information they teach you to solve these kinds of problems at school. :/

Hope I was fast enough :D

so Pro-T

What is wrong with y = -7 x /2 ?
.... and by the way we were given an expression, not an equation.
There is in fact no solution.

To Pro-Truth-Efficient:

If there would have been an equal sign (=), then I would have ALL the information. I do know how to solve equations, when equations are there.

lol -_- you don't need an equal sign

Ps, what grade are u in :/

He is a teacher. I am a retired Physics professor. Oobleck is a mathematician.

And without an equal sign you can not solve an equation.

HaHa, a Physics PROFESSOR wouldn't talk like that definitely, your probably just a 5th grader, who likes to pretend in his ways. Plus, what kind of name is Oobleck? There is no kind of rule in math anywhere that requires an equal sign for a problem like that :D

BtW I think I should change my name to something else, any suggestions?? :/

Yes, my suggestion is "not a mathematician" or "OOPS! Sorry about that". There IS NO equation without an equal sign or its equivalent such as < or >. 7x + 2y means nothing in any language except as a starting point for an equation. Son/daughter, you're talking to professors with Ph. D. degrees who know a lot more than you do about this subject. Humility goes a long way in these times. Good luck and we wish you well.
