So, here is exactly how you would do this:
-3m-2e if m=6 and e=1
We know the values of e and m. We can plug these in to evaluate.
Simply replace the number 6 in place of m and 1 in place of e in -3m-2e
-3m-2e Original expression
-3(6)-2(1) With values plugged in
-18-2 Simplified
-20 Final answer
Our final answer would therefore be: -20
