Solve the system by elimination.

y=x^2+2

-4x-y=10

Solve the system using substitution.

y=-3x^2+x-2

y=-5x+3

-4x-y=10

y=-3x^2+x-2

y=-5x+3

Both systems have no real roots.

If you graph the two curves, they do not intersect.

If you are interested in complex roots, eliminate y by comparison and solve for x. Substitute x into the equations to find y.
