1) Divide EVERYTHING by 3.
$$-3v+3x=12$$ $$3v-6x=-21$$ $$\frac{1}{3}(-3v+3x)=\frac{1}{3}(12)$$ $$ \frac{1}{3} (3v-6x)=\frac{1}{3}(-21)$$
Dividing by 3 is the same as multiplying by 1/3 right? @overtonka

I really don't know how to do this o.o
The multiplication property of equality allows you to multiply both sides of an equation by the same nonzero number and get an equivalent equation. Have you heard of this property in class?
No I havent
Let me give you an example let's say 3=3, now I multiply both sides by 2 what would I get?

Being interested in how and why things work is what math is all about
Do you want to learn how to do this?
Why the steps work?
Ryan is showing how to do it, he's not just giving answers
Thank you.
Let the learner decide.
ok, @overtonka , do you like the way skullpatrol does it or the way Ryan answers
