Given that the solution of the equation 7x-5m = 2 about X is m, then the value of M is? A. - 1 B.1 C. - 1 / 6 D.1 / 6. Please explain the process of solving the problem

Given that the solution of the equation 7x-5m = 2 about X is m, then the value of M is? A. - 1 B.1 C. - 1 / 6 D.1 / 6. Please explain the process of solving the problem

When the solution of the equation is m, i.e. x = m, the equation holds
Then: 7m-5m = 2
2m=2
m=1
