[ 1/1 Equation]
    Work: Find the solution of equation p = 100/(1+3.5%)-½ .
    Question type: Equation
    Solution:Original question:
      p = 100 ÷ (1 +
7
200
)(1 ÷ 2)
     Multiply both sides of the equation by:(1 +
7
200
)
      p (1 +
7
200
) = 100(1 ÷ 2)(1 +
7
200
)
    Remove a bracket on the left of the equation::
      p × 1 + p ×
7
200
= 100(1 ÷ 2)(1 +
7
200
)
    Remove a bracket on the right of the equation::
      p × 1 + p ×
7
200
= 1001 ÷ 2 × (1 +
7
200
)
    The equation is reduced to :
      p × 1 + p ×
7
200
= 100
1
2
(1 +
7
200
)
    The equation is reduced to :
     
207
200
p = 100
1
2
(1 +
7
200
)
    Remove a bracket on the right of the equation::
     
207
200
p = 100
1
2
× 1
1
2
×
7
200
    The equation is reduced to :
     
207
200
p = 100
1
2
7
400
    The equation is reduced to :
     
207
200
p =
39793
400

    The coefficient of the unknown number is reduced to 1 :
      p =
39793
400
÷
207
200
        =
39793
400
×
200
207
        =
39793
2
×
1
207

    We obtained :
      p =
39793
414
    This is the solution of the equation.

    Convert the result to decimal form :
      p = 96.118357
