Plugging inequalities into equations Let's say I have the inequality $3f \leq 2m$. If I wanted to plug this into the equation $n-m+f=2$, how would I do that? Where would I begin?

I assume that you can replace the $=$ sign with a $≤$ (less than OR equal to) so thus $n-m+f≤2$ adding gets $n-3m+4f≤2$
If your not sure of this use integers to test out this theory!! 
Ex:$3≤3$ and $6≤7$ so $9≤10$
Notice this only works when there is a $≤$ involved
