Question

determine the solution of the system

y = x + 6
y = 2x

Answer 1

2x=x+6, x=6, y=6+6, y=12, (6,12)

Answer 2

there you go, (6,12)

Answer 3

how'd you get the answer for the first one?

Answer 4

well, you have to substitute either one, like you can substitute y to 2x, then after you get 2x=x+6, you subtract the x and get x=6, from there substitute to the second the x and you get y=12

Answer 5

oh okay. thank you!

Answer 6

no problem
