Question

Plz help i will give medal and i will fan ^~^

Answer 1

Lol, #3 should be really easy:D Since they already give you Y, just plug that into the second equation and substitute:D. Like this:
You have to equations:
4x+y=18, y=x+3
4x+1(x+3)=18
Next step is to distribute:
4x+1x+3=18
Combine Like terms:
5x+3=18.
Instead of adding 3, you subtract it from both sides to get x by itself.
So now your equation looks like this:
5x=15.
Divide both sides by 5 And you get
x=3.

Answer 2

Now plug in the x into any equation. It doesn't really matter. You're going to get the same answer. I'll use:
y=x+3
y=1(3) + 3
y= 3+3
y=6.
Got it? Is there anything unclear?
