  Hello !!

  First you sum the equations to eliminate the [n].

  2m - n = 3

  +

  m + n = 9

  3m = 12

  Second, having eliminated the unknown [n] you solve the equation that came up to find the value of [m].

  3m = 12

  m = 12/3

  m = 4

  Third and last, you substitute the value of [m] you found in any of the equations and find the value of [n].

  m + n = 9

  4 + n = 9

  n = 9 - 4

  n = 5

  Final result : The solution for [m] is 4 and the solution for [n] is 5.

  I hope I have collaborated !
