i need help on an elimination problem. 12xsquared - 5ysquared=523 6xsquared + 2ysquared=482
i need to know the values of x and y
$$\\12x^2-5y^2=523 \qquad (1)\\ 6x^2+2y^2=482 \qquad \;\; (2) \rightarrow 12x^2+4y^2=964\qquad (2b)\\\\ (2b)-(1)\\\\ 4y^2-\;-5y^2=964-523\\ 9y^2=441\\ y=\pm 7$$
Can you finish it now?
