[ 1/1 Equation]
    Work: Find the solution of equation 750/x+1.5 = 750/(x+20) .
    Question type: Equation
    Solution:Original question:
     750 ÷ x +
3
2
= 750 ÷ ( x + 20)
     Multiply both sides of the equation by: x  ,  ( x + 20)
     750( x + 20) +
3
2
x ( x + 20) = 750 x
    Remove a bracket on the left of the equation::
     750 x + 750 × 20 +
3
2
x ( x + 20) = 750 x
    The equation is reduced to :
     750 x + 15000 +
3
2
x ( x + 20) = 750 x
    Remove a bracket on the left of the equation:
     750 x + 15000 +
3
2
x x +
3
2
x × 20 = 750 x
    The equation is reduced to :
     750 x + 15000 +
3
2
x x + 30 x = 750 x
    The equation is reduced to :
     780 x + 15000 +
3
2
x x = 750 x
    
    There are 0 solution(s).
