1 Answer

5m - 7+3m = 19 + 7m
 
1.  Simplify both sides
 
 
  5m - 7 = 19 + 7m
 
2 . Transposition and adding same quantity to both sides of equation are equivalent.
 
      5m - 7m = 19 + 7
 
 3.   -2m = 26
 
 4.  m = -26/2 = - 13
 
  4 steps has to be used in the same order in each case of solving the linear equations.
