    Work: Find the solution of equation (x-180)*(1-25%)/(1000+500) = (x-180-320)*(1-25%)/1000 .
    Question type: Equation
    Solution:Original question:
     ( x − 180)(1 −
25
100
) ÷ (1000 + 500) = ( x − 180 − 320)(1 −
25
100
) ÷ 1000
     Multiply both sides of the equation by:(1000 + 500)
     ( x − 180)(1 −
25
100
) = ( x − 180 − 320)(1 −
25
100
) ÷ 1000 × (1000 + 500)
