[ 1/1 Equation]
    Work: Find the solution of equation (20000+105000)/(34000+10000x) = (30+x)/6 .
    Question type: Equation
    Solution:Original question:
     (20000 + 105000) ÷ (34000 + 10000 x ) = (30 + x ) ÷ 6
     Multiply both sides of the equation by:(34000 + 10000 x )
     (20000 + 105000) = (30 + x ) ÷ 6 × (34000 + 10000 x )
    Remove a bracket on the left of the equation::
     20000 + 105000 = (30 + x ) ÷ 6 × (34000 + 10000 x )
    Remove a bracket on the right of the equation::
     20000 + 105000 = 30 ÷ 6 × (34000 + 10000 x ) + x ÷ 6 × (34000 + 10000 x )
    The equation is reduced to :
     20000 + 105000 = 5(34000 + 10000 x ) + x ×
