Solve the following simultaneous equations by subtitution: y = x² + y² = 5 and 3x + y = 1.

Pls help asap!​

Use substitution. Plug the 3x+1 into x2+y2=5 replacing the y .

This gives you an equation in just x , specifically x2+(3x+1)2=5 .

Solve this for x , it’s a simple quadratic equation.

Substitute that value (or those values) back into y=3x+1 to find y and you’ll be done.

You should end up with (−1,−2) and (25,115)

I hope that helps.
