    Work: Find the solution of equation (4-3t/(3-1/4t))×(2-t/(3-1/4t)) = 4 .
    Question type: Equation
    Solution:Original question:
     (43 t ÷ (31 ÷ 4 × t ))(2 t ÷ (31 ÷ 4 × t )) = 4
    Remove a bracket on the left of the equation::
     4(2 t ÷ (31 ÷ 4 × t ))3 t ÷ (31 ÷ 4 × t ) × (2 t ÷ (31 ÷ 4 × t )) = 4
     Multiply both sides of the equation by:(31 ÷ 4 × t )
     4(2 t ÷ (31 ÷ 4 × t ))(31 ÷ 4 × t )3 t (2 t ÷ (31 ÷ 4 × t )) = 4(31 ÷ 4 × t )
    Remove a bracket on the left of the equation:
     4 × 2(31 ÷ 4 × t )4 t ÷ (31 ÷ 4 × t ) × (31 ÷ 4 × t )3 t (2 t ÷ (31 ÷ 4 × t )) = 4(31 ÷ 4 × t )
    Remove a bracket on the right of the equation::
     4 × 2(31 ÷ 4 × t )4 t ÷ (31 ÷ 4 × t ) × (31 ÷ 4 × t )3 t (2 t ÷ (31 ÷ 4 × t )) = 4 × 34 × 1 ÷ 4 × t
    The equation is reduced to :
     8(31 ÷ 4 × t )4 t ÷ (31 ÷ 4 × t ) × (31 ÷ 4 × t )3 t (2 t ÷ (31 ÷ 4 × t )) = 121 t
     Multiply both sides of the equation by:(31 ÷ 4 × t )
     8(31 ÷ 4 × t )(31 ÷ 4 × t )4 t (31 ÷ 4 × t )3 t (2 t ÷ (31 ÷ 4 × t ))(31 ÷ 4 × t ) = 12(31 ÷ 4 × t )1 t (31 ÷ 4 × t )
    Remove a bracket on the left of the equation:
     8 × 3(31 ÷ 4 × t )8 × 1 ÷ 4 × t (31 ÷ 4 × t )4 t (31 ÷ 4 × t )3 = 12(31 ÷ 4 × t )1 t (31 ÷ 4 × t )
    Remove a bracket on the right of the equation::
     8 × 3(31 ÷ 4 × t )8 × 1 ÷ 4 × t (31 ÷ 4 × t )4 t (31 ÷ 4 × t )3 = 12 × 312 × 1 ÷ 4 × t 1 t (31 ÷ 4 × t )
    The equation is reduced to :
     24(31 ÷ 4 × t )2 t (31 ÷ 4 × t )4 t (31 ÷ 4 × t )3 t (2 t ÷ (31 ÷ 4 × t ))(31 ÷ 4 × t ) = 363 t 1 t (31 ÷ 4 × t )
    Remove a bracket on the left of the equation:
     24 × 324 × 1 ÷ 4 × t 2 t (31 ÷ 4 × t )4 t (31 ÷ 4 × t ) = 363 t 1 t (31 ÷ 4 × t )
    Remove a bracket on the right of the equation::
     24 × 324 × 1 ÷ 4 × t 2 t (31 ÷ 4 × t )4 t (31 ÷ 4 × t ) = 363 t 1 t × 3 + 1 t × 1 ÷ 4 × t
    The equation is reduced to :
