(1) When the equation 2x + M = 3 and x-one-third = one-third m of X have equal solutions, how to find the value of M? (2) When m is a value, the solution of the equation 5x + 4m = two-thirds + X is 3 less than that of X (M + 2) = m (x + 2) (3) When m is an integer, the solution of the equation 2mx = (M + 1) x + 6 is a positive integer

1、M=7/5
2、m=-2/3
3. 2mx = MX + X + 6 gives x = 6 / (m-1)
When x = 1, i.e. 6 / (m-1) = 1, M = 7 / 1
When x = 2, i.e. 6 / (m-1) = 2, M = 8 / 2
When x = 3, i.e. 6 / (m-1) = 3, M = 9 / 3
By analogy, M = (6 + n) / N (n is a natural number)
