What are the solutions to the nonlinear system of equations bellow: X sq + Y sq = 16 X sq/ 4 sq - Y sq / 4 sq = 1

OpenStudy (loser66):

Replace Xsq = 16-Ysq into the second equation, solve for Y, then replace back to either of them to solve for X

OpenStudy (anonymous):

ok what I did was I solved for y sq for the first problem and got 16 - x sq / 4 sq - x sq / 4 sq = 1

OpenStudy (anonymous):

i divide both sides by 4 sq right?

OpenStudy (loser66):

Nope. You made mistake there.
