Question

How do you solve `12-3+ 4m - 6( 3m - 2)]= - 7( 2m - 8) - 3( m - 2) + 3m - 5`?

Answer 1

m has no solution.

Explanation:

Expand the brackets:
`12-3+4m-18m+12 = -14m+56-3m+6+3m-5`

Group the like-terms:
`21-14m = -14m+57`

Rearrange to get `m` on one side:
`-14m+14m = 57-21`

`0 = 36`

Since `0 = 36` is a contradiction there is no solution for m which satisfies the equation.
