How do you solve the system #y^2+x=2# and #3x+y=8#? Precalculus Solving Systems of Two Equations Solving by Substitution 1 Answer Noah G Jul 4, 2016 #x = 2 - y^2# #:.3(2 - y^2) + y = 8# #6 - 3y^2 + y = 8# #0 = 3y^2 - y + 2# #y = (-(-1) +- sqrt(-1^2 - 4 xx 3 xx 2))/(2 xx 3)# #y = (1 +- sqrt(-23))/6# #y = O/# #:.# This systems of equations has no real solution.
