To check whether 8 is the solution.
2m = 18
2m - 18 = 0
L.H.S. = 2m - 18
Putting m = 8
= 2 ( 8 ) - 18
= 16 - 18
= - 2
≠ R.H.S.
Hence, m = 8 is not a solution.
2m = 18
2m - 18 = 0
L.H.S. = 2m - 18
Putting m = 8
= 2 ( 8 ) - 18
= 16 - 18
= - 2
≠ R.H.S.
Hence, m = 8 is not a solution.

No
If we substitute m=8 in the equation 2m = 18
we get..
2*8=18
16= 18
But 16 does not equal to 18
Hence proved
