[ 1/1 Equation]
    Work: Find the solution of equation 2 = (1600/(850-x))+(1600/(55-x)) .
    Question type: Equation
    Solution:Original question:
     2 = (1600 ÷ (850 − x )) + (1600 ÷ (55 − x ))
    Remove a bracket on the right of the equation::
     2 = 1600 ÷ (850 − x ) + (1600 ÷ (55 − x ))
     Multiply both sides of the equation by:(850 − x )
     2(850 − x ) = 1600 + (1600 ÷ (55 − x ))(850 − x )
    Remove a bracket on the left of the equation:
     2 × 850 − 2 x = 1600 + (1600 ÷ (55 − x ))(850 − x )
    Remove a bracket on the right of the equation::
     2 × 850 − 2 x = 1600 + 1600 ÷ (55 − x ) × (850 − x )
    The equation is reduced to :
     1700 − 2 x = 1600 + 1600 ÷ (55 − x ) × (850 − x )
     Multiply both sides of the equation by:(55 − x )
     1700(55 − x ) − 2 x (55 − x ) = 1600(55 − x ) + 1600(850 − x )
    Remove a bracket on the left of the equation:
     1700 × 55 − 1700 x − 2 x (55 − x ) = 1600(55 − x ) + 1600(850 − x )
    Remove a bracket on the right of the equation::
     1700 × 55 − 1700 x − 2 x (55 − x ) = 1600 × 55 − 1600 x + 1600(850 − x )
    The equation is reduced to :
     93500 − 1700 x − 2 x (55 − x ) = 88000 − 1600 x + 1600(850 − x )
    Remove a bracket on the left of the equation:
     93500 − 1700 x − 2 x × 55 + 2 x x = 88000 − 1600 x + 1600(850 − x )
    Remove a bracket on the right of the equation::
     93500 − 1700 x − 2 x × 55 + 2 x x = 88000 − 1600 x + 1600 × 850 − 1600 x
    The equation is reduced to :
     93500 − 1700 x − 110 x + 2 x x = 88000 − 1600 x + 1360000 − 1600 x
    The equation is reduced to :
     93500 − 1810 x + 2 x x = 1448000 − 3200 x
    
    There are 0 solution(s).
