Question

23 + 8m + 4n - 5m - 27​

Answer 1

`-4 + 3m + 4n`

Explanation:

In this question, you are combining like terms, meaning doing equations to numbers that fit with only each other.

So we should start on the number without variables:

23 and 27

Match them up together and you should find your first equation:

23 - 7

==> -4

So we should have -4 + 8m + 4n - 5m

Now we should combine the numbers with the variable of m:

8m and 5m

Match them up together and you should find your first equation:

8m - 5m

==> 3m

So we should now have -4 + 3m + 4n

Since there are no other variables of n, we are all done:

-4 + 3m + 4n is your final answer
