What is the value of m in the equation 1/2m-3/4m=16, when n = 8

I assume that one of the two "m"s in the given is actually an n, to which I can substitute n = 8.

If this is (1/2) m - (3/4) n = 16:

Then (1/2) m - (3/4) (8) = 16

(1/2) m = 22

m = 44

But if this is (1/2) n - (3/4) m = 16:

Then (1/2) (8) - (3/4) m = 16

4 - (3/4) m = 16

(3/4) m = - 12

m = - 16
