[ 1/1 Equation]
    Work: Find the solution of equation (4.156-y)*0.0003174*(1280000+80000*y) = 0 .
    Question type: Equation
    Solution:Original question:
     (
1039
250
y ) ×
1587
5000000
(1280000 + 80000 y ) = 0
    Remove the bracket on the left of the equation:
     Left side of the equation =
1039
250
×
1587
5000000
(1280000 + 80000 y ) y ×
1587
5000000
(1280000 + 80000 y )
                                             =
1648893
1250000000
(1280000 + 80000 y ) y ×
1587
5000000
(1280000 + 80000 y )
                                             =
1648893
1250000000
× 1280000 +
1648893
1250000000
× 80000 y y ×
1587
5000000
(1280000 + 80000 y )

    After the equation is converted into a general formula, it is converted into:
    ( y + 16 )( 250y - 1039 )=0
    From
        y + 16 = 0
        250y - 1039 = 0

    it is concluded that::
        y1=-16
        y2=
1039
250
    
    There are 2 solution(s).
