[ 1/1 Equation]
    Work: Find the solution of equation (3x+10)*42x/(7x+10)-18x = 32 .
    Question type: Equation
    Solution:Original question:
     (3 x + 10) × 42 x ÷ (7 x + 10)18 x = 32
     Multiply both sides of the equation by:(7 x + 10)
     (3 x + 10) × 42 x 18 x (7 x + 10) = 32(7 x + 10)
    Remove a bracket on the left of the equation::
     3 x × 42 x + 10 × 42 x 18 x (7 x + 10) = 32(7 x + 10)
    Remove a bracket on the right of the equation::
     3 x × 42 x + 10 × 42 x 18 x (7 x + 10) = 32 × 7 x + 32 × 10
    The equation is reduced to :
     126 x x + 420 x 18 x (7 x + 10) = 224 x + 320
    Remove a bracket on the left of the equation:
     126 x x + 420 x 18 x × 7 x 18 x × 10 = 224 x + 320
    The equation is reduced to :
     126 x x + 420 x 126 x x 180 x = 224 x + 320
    The equation is reduced to :
     126 x x + 240 x 126 x x = 224 x + 320

    the solutions is:
        x1=20
    
    There are 1 solution(s).
