To solve the system of equations below, zach isolated x in the first equation
and then substituted it into the second equation. what was the resulting
equation?
(x + y² = 25

"To solve the system of equations Zach isolated x^2 into the first equation and then substituted it into the second equation.What was the resulting equation

x^2 + y^2 = 25

x^2 / 16 - y^2 / 9 = 1

is the resulting equation
