[ 1/1 Equation]
    Work: Find the solution of equation 1447*3*（1+16*1000/(1000+2000）*（1+0.05） ) = y .
    Question type: Equation
    Solution:Original question:
     1447 × 3(1 + 16 × 1000 ÷ (1000 + 2000) × (1 +
1
20
)) = y
    Remove a bracket on the left of the equation:：
     1447 × 3 × 1 + 1447 × 3 × 16 × 1000 ÷ (1000 + 2000) × (1 +
1
20
) = y
    The equation is reduced to :
     4341 + 69456000 ÷ (1000 + 2000) × (1 +
1
20
) = y
     Multiply both sides of the equation by:(1000 + 2000)
     4341(1000 + 2000) + 69456000(1 +
1
20
) = y (1000 + 2000)
    Remove a bracket on the left of the equation:
     4341 × 1000 + 4341 × 2000 + 69456000(1 +
1
20
) = y (1000 + 2000)
    Remove a bracket on the right of the equation:：
     4341 × 1000 + 4341 × 2000 + 69456000(1 +
1
20
) = y × 1000 + y × 2000
    The equation is reduced to :
     4341000 + 8682000 + 69456000(1 +
1
20
) = y × 1000 + y × 2000
    The equation is reduced to :
     13023000 + 69456000(1 +
1
20
) = 3000 y
    Remove a bracket on the left of the equation:
     13023000 + 69456000 × 1 + 69456000 ×
1
20
 = 3000 y
    The equation is reduced to :
     13023000 + 69456000 + 3472800 = 3000 y
    The equation is reduced to :
     85951800 = 3000 y

    Transposition :
      - 3000 y = - 85951800

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     85951800 = 3000 y

    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 :
     3000 y = 85951800

    The coefficient of the unknown number is reduced to 1 :
      y = 85951800 ÷ 3000
        = 85951800 ×
1
3000
        = 143253 ×
1
5

    We obtained :
      y =
143253
5
    This is the solution of the equation.

    Convert the result to decimal form :
      y = 28650.6
