[ 1/1 Equation]
    Work: Find the solution of equation 12000/(80-20x)+13200/(80+15x) = 160 .
    Question type: Equation
    Solution:Original question:
     12000 ÷ (8020 x ) + 13200 ÷ (80 + 15 x ) = 160
     Multiply both sides of the equation by:(8020 x )
     12000 + 13200 ÷ (80 + 15 x ) × (8020 x ) = 160(8020 x )
    Remove a bracket on the left of the equation::
     12000 + 13200 ÷ (80 + 15 x ) × 8013200 ÷ (80 + 15 x ) × 20 x = 160(8020 x )
    Remove a bracket on the right of the equation::
     12000 + 13200 ÷ (80 + 15 x ) × 8013200 ÷ (80 + 15 x ) × 20 x = 160 × 80160 × 20 x
    The equation is reduced to :
     12000 + 1056000 ÷ (80 + 15 x )264000 ÷ (80 + 15 x ) × x = 128003200 x
     Multiply both sides of the equation by:(80 + 15 x )
     12000(80 + 15 x ) + 1056000264000 x = 12800(80 + 15 x )3200 x (80 + 15 x )
    Remove a bracket on the left of the equation:
     12000 × 80 + 12000 × 15 x + 1056000264000 x = 12800(80 + 15 x )3200 x (80 + 15 x )
    Remove a bracket on the right of the equation::
     12000 × 80 + 12000 × 15 x + 1056000264000 x = 12800 × 80 + 12800 × 15 x 3200 x (80 + 15 x )
    The equation is reduced to :
     960000 + 180000 x + 1056000264000 x = 1024000 + 192000 x 3200 x (80 + 15 x )
    The equation is reduced to :
     201600084000 x = 1024000 + 192000 x 3200 x (80 + 15 x )
    Remove a bracket on the right of the equation::
     201600084000 x = 1024000 + 192000 x 3200 x × 803200 x × 15 x
    The equation is reduced to :
     201600084000 x = 1024000 + 192000 x 256000 x 48000 x x
    The equation is reduced to :
     201600084000 x = 102400064000 x 48000 x x
    
    There are 0 solution(s).
