Question

what is the solution to the following system of equations? y=x^2+x+8; y=x^2+2x+5

Answer 1

You just have to use either linear combination or substitution. Hope you can get it from there.

Answer 2

?

Answer 3

How do i do that?

Answer 4

U could set them equal to each other like this...
x^2+x+8 = x^2+2x+5
Solve for x.
Then, plug in the value u get for x in any of the two equations to find y!

Answer 5

x^2+x+8 = x^2+2x+5
solve it you'll get x = 3 and then put this value of "x" in any of equation..
you'll get y=20
