Question

Help? Solve using substitution.
y = x - 2
x + y = 10

Answer 1

y=4
x=6

Answer 2

Tell me if you need the steps. :)

Answer 3

you have y = x -2 and x + y = 10

so you plug in y into the second function.
so it will be x + x -2 = 10

2x = 12
x = 6.

Plug this value in any of the two function and it will give you the y-value.

Answer 4

Great, thank you so much!

Who are you referring to?

Answer 6

Both of you. I merely needed the answers, but the explanation will help me get the rest of the problems.
