Answer: So your answers are m=1,n=-4.
Step-by-step explanation:Ok... So what you do is that you make one variable equal something. Take the second equation.
m+3n=-11 could be written as m=-3n-11 by moving the 3n over. Then, you plug in m for the first equation. You then have
2(-3n-11)-3n=14
-6n-22-3n=14
-9n=36
n=-4
Then plug in n for the other equation.
m=-3(-4)11
m=12-11
m=1
When moving numbers or variables over, you do the opposite. So, if you have m+3=3m and you wanted to move the m over, then you would subtract m. If m was negative, then you would add it.
-m+3=3m.
Hope this helps :D
