Question

How do i do this step by step:
Solve the system by the substitution method.

x^2 + y^2 = 113
x + y = 15

Answer 1

second equation is the same as \(y=15-x\) so you can substitute in the first equation to get
\[x^2+(15-x)^2=113\] and solve the resulting quadratic

Answer 2

So you substitute the y with the 15-x right?

Answer 3

yes

Answer 4

ok
