49x^2+16y^2+160y=384 having problem sloving for x
Follow Math Help Forum on Facebook and Google+
x can only be solved in terms of y.
Move all terms independant of x to the right hand side, divide by 49 and take the square root.
Is this what you are meaning 49x^2=16y^2+160y-384
I tried it the way I sent it and it was way way wrong... please help
