    you have the expression for x^2 from the first equation. go ahead and use this expression in the second equation every time you see x^2 then solve the equation with the one variable

    \(\large x^2 + y^2 = 25\) so whoever it was in the q isolated x^2 from the 1st equation... yeah? so would look like \(\large x^2 + y^2 = 25\) \(\large x^2 = 25 - y^2\) I'm proly goin whay too slow, but you with me so far?

    cool, so next they subbed this : \(\large \color{red} {x^2 = 25 - y^2}\) into the 2nd equation: \(\huge \frac{x^2}{16} - \frac{y^2}9 = 1\) so would look something like this: \(\huge \frac{x^2}{16} - \frac{y^2}9 = 1\) \(\huge \frac{\color{red} {25 - y^2}}{16} - \frac{y^2}9 = 1\) so u still with me man, any q's so far?

    cool man... so that's the resulting equation... u can solve it if u want, but the above's pretty much all they're lookin for in the q
