[ 1/1 Equation]
    Work: Find the solution of equation (100/115)*x-(10/12)*(x-4)/(100/115)*x = 0.05 .
    Question type: Equation
    Solution:Original question:
     (100 ÷ 115) x (10 ÷ 12)( x 4) ÷ (100 ÷ 115) × x =
1
20
     Multiply both sides of the equation by:(100 ÷ 115)
     (100 ÷ 115) x (100 ÷ 115)(10 ÷ 12)( x 4) x =
1
20
(100 ÷ 115)
    Remove a bracket on the left of the equation::
     100 ÷ 115 × x (100 ÷ 115)(10 ÷ 12)( x 4) x =
1
20
(100 ÷ 115)
    Remove a bracket on the right of the equation::
     100 ÷ 115 × x (100 ÷ 115)(10 ÷ 12)( x 4) x =
1
20
× 100 ÷ 115
    The equation is reduced to :
     
20
23
x (100 ÷ 115)(10 ÷ 12)( x 4) x =
1
23
    Remove a bracket on the left of the equation:
     
20
23
x × 100 ÷ 115(10 ÷ 12)( x 4) x =
1
