Question

Solve the following system.

(picture)

Do I just add the two together?

Answer 1

Since y = x^2 + 4, we can replace the 'y' in the second equation with x^2+4 to go from


y - 4x = 1

to

x^2+4 - 4x = 1


Now solve for x

Answer 2

I got x=1 & x=3

Answer 3

now use those x values to find the corresponding y values

Answer 4

so when x = 1, y = ???

and

when x = 3, y = ???

Answer 5

To I put it into the first equation this time?

Answer 6

either equation works

Answer 7
