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

According to question,

To solve the given system of Equations  Zach isolated from  the first equation

Given first equation is:

Separating term, we get

  ------ eqn 1

And then substituted it into the second equation which is given below:-

Substituting eqn 1 in above equation we get,

Which is the required equation

step-by-step explanation:

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
