can you just walk me through it from the beginning

Answer 6

okk, but you'll have to try to solve it with me,
when you plug in,
\(y^2=25-x^2\) from 2nd equation, in 1st one,
you get
\(\dfrac{x^2}{25}+\dfrac{25-x^2}{100}=1\)
right ?
we separate it like this :
\(\dfrac{x^2}{25}+\dfrac{25}{100}-\dfrac{x^2}{100}=1\)
now can you try to combine like terms ? terms containing x^2 and constants ?
