[ 1/1 Equation]
    Work: Find the solution of equation 51÷[1+4(2x+7)]+11 = 10 .
    Question type: Equation
    Solution:Original question:
     51 ÷ (1 + 4(2 x + 7)) + 11 = 10
     Multiply both sides of the equation by:(1 + 4(2 x + 7))
     51 + 11(1 + 4(2 x + 7)) = 10(1 + 4(2 x + 7))
    Remove a bracket on the left of the equation::
     51 + 11 × 1 + 11 × 4(2 x + 7) = 10(1 + 4(2 x + 7))
    Remove a bracket on the right of the equation::
     51 + 11 × 1 + 11 × 4(2 x + 7) = 10 × 1 + 10 × 4(2 x + 7)
    The equation is reduced to :
     51 + 11 + 44(2 x + 7) = 10 + 40(2 x + 7)
    The equation is reduced to :
     62 + 44(2 x + 7) = 10 + 40(2 x + 7)
    Remove a bracket on the left of the equation:
     62 + 44 × 2 x + 44 × 7 = 10 + 40(2 x + 7)
    Remove a bracket on the right of the equation::
     62 + 44 × 2 x + 44 × 7 = 10 + 40 × 2 x + 40 × 7
    The equation is reduced to :
     62 + 88 x + 308 = 10 + 80 x + 280
    The equation is reduced to :
     370 + 88 x = 290 + 80 x

    Transposition :
     88 x 80 x = 290370

    Combine the items on the left of the equation:
     8 x = 290370

    Combine the items on the right of the equation:
     8 x = - 80

    The coefficient of the unknown number is reduced to 1 :
      x = - 80 ÷ 8
        = - 80 ×
1
8
        = - 10 × 1

    We obtained :
      x = - 10
    This is the solution of the equation.
