Answer:

Step-by-step explanation:

[tex]y=4+x[/tex]          ............................................ (1)

[tex]y=x^2+x-12[/tex]  ............................................ (2)

now equate both (1) and (2)

[tex]4+x=x^2+x-12[/tex]

[tex]=>x^2=16[/tex]

[tex]x=-4,4[/tex]

now substitute the values of x ,

when [tex]x=-4[/tex] , y becomes 0

when [tex]x=4[/tex]  , y becomes 8

so, solution set:

[tex](-4,0)[/tex] and [tex](4,8)[/tex]
