Divide the first by 3 and something magic may pop out.

- skullpatrol

I tried to teach you this yesterday and you refused to learn?

- anonymous

I did not refuse I just didn't get it

Well, @overtonka, I think @skullpatrol would be delighted to see you make a better effort, today.
Divide the first equation by 3 and show what you get.

- anonymous

-1v-1x=5

- tkhunny

Super! Any suggestion what we should do next?
Hint: I didn't have you divide by 3 just for fun.

- anonymous

solve for one of the variables?

- skullpatrol

Yes!

- anonymous

so 1v=5-1x?

- skullpatrol

Now what (hint: use the name of the method)

- tkhunny

Since we are using substitition, that would be the things to do.
Please abandon those silly-looking '1's. We don't usually write those unless we are trying to make a point.

- anonymous

ok
so v-x=5?

- tkhunny

No, why did you UNsolve? Please "solve for one of the variables".

- anonymous

v=5-x?

- skullpatrol

Correct.

- anonymous

so plug that in to the other equation?

- skullpatrol

Substitution principle:
An expression maybe replaced by another expression that has the same value
If $$a=b$$then b maybe substituted for a in any expression.

- tkhunny

It's your big chance. Let's see the substitution!
