Question

10m-p=-n for m

Answer 1

get m on its own.

add p to both sides.
divide both sides by 10

Answer 2

10m - p = -n
10m - p + p = -n + p
10m = -n + p
10m/10 = -n + p / 10
m = -n + p / 10

Answer 3

Wait i got it now
Thanks

Answer 4

very nearly almost perfect.

but the second to last line, you divided m by 10, p by 10, but forgot to divide -n by 10

Answer 5

@JamesWolf whoops.... so the correct way ?

Answer 6

so exactly what you did, only
10m/10 = -n/10 + p/10
m = -n/10 + p/10

and if you want you can write that slightly simpler as
m = (p - n)/10
