Question

To solve the system of equations below, Pedro isolated the variable y in the first equation and then substituted it into the second equation. What was the resulting equation? { 5y=10x {x^2+y^2=36

Answer 1

Answer:

Resulting equation will be 5x²=36.

Step-by-step explanation:

The given equations are 5y = 10x-----(1)

and x²+y²=36------(2)

Now we substitute the value of y from equation (1) into equation (2).

5y = 10x ⇒ y = 2x

Then equation (2) will be x²+(2x)²=36

x²+4x²=36 ⇒ 5x² = 36

So the equation after substitution of the value of y from equation 1 will be 5x² = 36.
