[ 1/1 Equation]
    Work: Find the solution of equation 2/12×(m-1)-4/4-3m = 1-1/12-2m .
    Question type: Equation
    Solution:Original question:
     2 ÷ 12 × ( m − 1) − 4 ÷ 4 − 3 m = 1 − 1 ÷ 12 − 2 m
     Left side of the equation =
1
6
( m − 1) − 1 − 3 m
    The equation is transformed into :
     
1
6
( m − 1) − 1 − 3 m = 1 − 1 ÷ 12 − 2 m
    Remove the bracket on the left of the equation:
     Left side of the equation =

m =
25
12

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
      -
25
12
=

m

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
5

    This is the solution of the equation.

    Convert the result to decimal form :
      m = - 2.5
