Question

write the ordered pair that is the solution to the system of equations.
y=2x+2
y=x-1

Answer 1

you know y = x - 1
so substitute x - 1 in for y in the top equation

Answer 2

X=-3, Y=-2. You will get this solution if you d what blurbendy suggested.

Answer 3

but how do you get that.?

Answer 4

Alright here's how I got it.

Answer 5

wouldn't y=-4 because of the -1 not +1.?

Answer 6

Oh you're right, I overlooked the signs there.

Answer 7

so it would be (-3,-4)

Answer 8

Yes that's the solution set!

Answer 9

thank you :)
