    Work: Find the solution of equation 90/(14-(x/(24+x-60)) ) = 60+x/24 .
    Question type: Equation
    Solution:Original question:
     90 ÷ (14( x ÷ (24 + x 60))) = 60 + x ÷ 24
     Multiply both sides of the equation by:(14( x ÷ (24 + x 60)))
     90 = 60(14( x ÷ (24 + x 60))) + x ÷ 24 × (14( x ÷ (24 + x 60)))
    Remove a bracket on the right of the equation::
     90 = 60 × 1460( x ÷ (24 + x 60)) + x ÷ 24 × (14( x ÷ (24 + x 60)))
    The equation is reduced to :
     90 = 84060( x ÷ (24 + x 60)) + x ×
