Which equation can be solved by using this system of equations?

startlayout enlarged left-brace 1st row y = 3 x superscript 5 baseline minus 5 x cubed + 2 x squared minus 10 x + 4 2nd row y = 4 x superscript 4 baseline + 6 x cubed minus 11 endlayout

3 x superscript 5 baseline minus 5 x cubed + 2 x squared minus 10 x + 4 = 0

3 x superscript 5 baseline minus 5 x cubed + 2 x squared minus 10 x + 4 = 4 x superscript 4 baseline + 6 x cubed minus 11

3 x superscript 5 baseline + 4 x superscript 4 baseline + x cubed + 2 x squared minus 10 x minus 7 = 0

4 x superscript 4 baseline + 6 x cubed minus 11 = 0
