## Discord 3 years ago 3m - 2n + 4p = 15 m - n + p = 3 m + 4n - 5p = 0 System of equations

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

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?

5. Discord

Wait what does m equal?

6. micahwood50

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

7. Discord

Oh okay.

8. micahwood50

You know what to do?

9. Discord

I think so. Lemme try and solve it.
