Hello there, Discord. Rainbow Dash is here to help. Isolate any variable in the first equation then plug it to either second or third equation. Does this make sense?

And I could use some clarification

4. micahwood50 Group Title

Saying, I want to isolate m in first equation.$3m - 2n + 4p = 15$$3m = 15 + 2n - 4p$$m = \frac{15 + 2n - 4p}{3} = 5 + \frac{2}{3}n - \frac{4}{3}p$ Ok, now I know m. Plug it into second or third equation. Does that make sense?

Wait what does m equal?

6. micahwood50 Group Title

$m = 5 + \frac{2}{3}n - \frac{4}{3}p$

7. Discord Group Title

Oh okay.

8. micahwood50 Group Title

You know what to do?

9. Discord Group Title

I think so. Lemme try and solve it.
