Given that,
(6m + 1)/3 + 1 = (m - 3)/6
or, (6m + 1 + 3)/3 = (m - 3)/6
or, (6m + 4)/3 = (m - 3)/6
or, 6 (6m + 4)/3 = m - 3
or, 2 (6m + 4) = m - 3
or, 12m + 8 = m - 3
or, 12m - m = - 3 - 8
or, 11m = - 11
or, m = - 11/11
or, m = - 1
Therefore, the required solution be .
Given that,
5b - 2 (2b - 7) = 2 (3b - 1) + 7/2
or, 5b - 4b + 14 = 6b - 2 + 7/2
or, b + 14 = 6b - 2 + 7/2
or, 6b - b = 14 + 2 - 7/2
or, 5b = (28 + 4 - 7)/2
or, 5b = 25/2
or, b = 25/(2 × 5)
or, b = 5/2
Therefore, the required solution be

=> On multiplying { 6m + 4 } by 6 and { m - 3} by 3
=> we get ,
=> 36m + 24 = 3m - 9
=> 36m - 3m = { - 9 } - 24
=> 33m = { - 33 }
=> m =>
=> m = - 1
♧ 5b - 2 ( 2b - 7 ) = 2( 3b - 1 ) +
=> 5b - 4b + 14 = ( 6b - 2 ) +
On taking L.C.M. of R.H.S.
=> b + 14 = [ 12b - 4 + 7 ] / 2
=> b + 14 = [ 12b + 3 ] / 2
On multiplying { b - 14 } by 2 ,
=> 2b + 28 = 12b + 3
=> 2b - 12b = 3 - 28
=> - 10b = - 25
=> b = 25 / 10
=> b = 5 / 2 or 2.5
