Question

please HELPPP

Solve the following system of equations and show all work.

y = x2 + 3
y = x + 5

Answer 1

is there anything added on to the problems?

Answer 2

No, Just the equations above. I believe i'm suppose to use elimination but i'm a bit confused sense there is a exponent

Answer 3

Hint* You see that in both equations... y = something right?

Well if we know y = both of those things...then logically, both those things are equal right?

i.e
\[\large y = y\]

so

\[\large x^2 + 3 = x + 5\]

Now can you solve it?

Answer 4

x=-1 and x=2

Answer 5

Perfect...so now that we know the 'x' answers, we can find out the 'y' answers

*as there are clearly 2 sets of answers*

So when x = -1...what does either equation come out to?

Answer 6

And then when x = 2, what does either equation come out to?

Answer 7

alright so you have 4 and 7
