Step by step explanation:

Lets solve the first equation for y:

[tex]2x^2=5+y[/tex][tex]2x^2-5=y[/tex][tex]y=2x^2-5[/tex]

And replacing that value in the second equation we have:

[tex]4y=16x^2-60[/tex][tex]4(2x^2-5)=-20+8x^2[/tex][tex]8x^2-20=-20+8x^2[/tex]

Answer:

After replacing we have:

[tex]8x^2-20=-20+8x^2[/tex]
