Since both are already in y =, set them equal to each other and solve for X. What do you get as your X for the first one?

i'm not sure, i'm pretty terrible at math

fortytherapper · Answer

Alright, lets set them equal

X + 5 = X^2 - X + 2

When solving X, you wanna do the opposite operations until you get X by itself. So on the left, we have a positive 5. Since we do opposites, we would subtract 5 on both sides

anonymous · Answer

so both of these systems (number 3) are equal to y, meaning that they are equal to one another
ex: 4+5=y
      3+6=y 
      4+5=3+6
they both equal 9
in the same sense you equal both of these equations to one another
y = x + 5
y = x^2 - x + 2
will be
x + 5=x^2 - x + 2
from here solve
(tell me what you get and i will confirm)

anonymous · Answer

and this process is used to answer number 4 as well

qwertyzxv · Answer

it has to be a solution like (0,0) i think i need a graph

anonymous · Answer

ok so after you set them equal to each other you will get the answer for x which you will simply have to plug back into the system and get y
so your first answer will be the x and then plug in to get y 
(x,y)
