In an expression, the m-terms are 8m, -3m and km, and after combining only the m-terms the result is 0m (they cancel out completely). There are also separate n-terms that combine to 6n. If the final simplified expression is just 6n, what is the value of k?

Question

Accepted Answer

-5. The m-terms must sum to 0: 8 + (-3) + k = 0, so 5 + k = 0, giving k = -5. Then only 6n remains.

In an expression, the m-terms are 8 $m, - 3 m$ and km, and after combining only the m-terms the result is 0 $m$ (they cancel out completely).
There are also separate n-terms that combine to $6 n$ .
If the final simplified expression is just $6 n$ , what is the value of k?
