{x+y=5x2+y2=132 cases; Case 1: x plus y equals 5; Case 2: x squared plus y squared equals 13 end-cases; From the first equation: Step 2: Substitute

Solve for that variable, then plug it back to find the second coordinate. : {x+y=5x2+y2=132 cases; Case 1: x plus y equals

Multiply one or both equations by numbers so that the coefficients of one variable become opposites (e.g., -5ynegative 5 y Add the equations to eliminate that variable. {x+y=5x2+y2=132 cases; Case 1: x plus y equals
