Question

k = am+3mx what is the value of m in terms of a,k and x

Answer 1

If you mean solve for m.. then:
\[\LARGE k=am+3mx\]
Factor out m:
\[\LARGE k=m(a+3x)\]
Now divide:
\[\LARGE \frac{k}{a+3x}=m\]

Answer 2

you can start on the right side of the equation by noticing that both terms have "m" in them... "am" and "3mx"

So you can factor the right side like: m(a + 3x)

Answer 3

and welcome 2 os ;)
