Question 11591
I can why you are having so much trouble finding x, I can't see it anywhere either.

But the good news is, you got the right answer for m, congratulations, you did everything right and m = 1/2

Here's the check:

{{{-2m = 16m - 9}}} Substitute m = 1/2

{{{-2(1/2) = 16(1/2) - 9}}} Simplify.

{{{-1 = 8 - 9}}}

{{{-1 = -1}}} OK.
