[ 1/1 Equation]
    Work: Find the solution of equation 20000/x+17600/(x+30) = 10000/70 .
    Question type: Equation
    Solution:Original question:
     20000 ÷ x + 17600 ÷ ( x + 30) = 10000 ÷ 70
     Multiply both sides of the equation by: x
     20000 + 17600 ÷ ( x + 30) × x = 10000 ÷ 70 × x
     Multiply both sides of the equation by:( x + 30)
     20000( x + 30) + 17600 x = 10000 ÷ 70 × x ( x + 30)
    Remove a bracket on the left of the equation:
     20000 x + 20000 × 30 + 17600 x = 10000 ÷ 70 × x ( x + 30)
    Remove a bracket on the right of the equation::
     20000 x + 20000 × 30 + 17600 x = 10000 ÷ 70 × x x + 10000 ÷ 70 × x × 30
    The equation is reduced to :
     20000 x + 600000 + 17600 x =
1000
