Best ResponseYou've already chosen the best response.1that's right! now solve one equation for y or x. I would suggest you rewrite the second equation as y = 46 + x (just take x to the other side). Now put (46 + x) into y in the first equation.

Best ResponseYou've already chosen the best response.1everything will be in terms of y, so you can solve for y. Then plug y back into 2nd equation and you will find x!
