Respuesta :

To answer this question, try to solve the system of equations.  Start by plugging in "[tex]x^{2} +3x-7[/tex]" in for y in the second equation:

[tex]x^{2} +3x-7-5x+8=0[/tex]

*Combine like terms*

[tex]x^{2} -2x+1=0[/tex]

*Factor*

[tex](x-1)(x-1)=0[/tex]

*Set each term equal to 0*

x-1=0

*Add 1 to both sides*

x=1


C) There is exactly 1 solution.


Hope this helps!!
