[ 1/1 Equation]
    Work: Find the solution of equation 1/(1/150+1/510)*I-3 = (0.02-I)*8400/43 .
    Question type: Equation
    Solution:Original question:
     1 ÷ (1 ÷ 150 + 1 ÷ 510) × I − 3 = (
1
50
 − I ) × 8400 ÷ 43
     Multiply both sides of the equation by:(1 ÷ 150 + 1 ÷ 510)
     1 I − 3(1 ÷ 150 + 1 ÷ 510) = (
1
50
 − I ) × 8400 ÷ 43 × (1 ÷ 150 + 1 ÷ 510)
    Remove a bracket on the left of the equation:：
     1 I − 3 × 1 ÷ 150 − 3 × 1 ÷ 510 = (
1
50
 − I ) × 8400 ÷ 43 × (1 ÷ 150 + 1 ÷ 510)
    Remove a bracket on the right of the equation:：
     1 I − 3 × 1 ÷ 150 − 3 × 1 ÷ 510 =
1
50
 × 8400 ÷ 43 × (1 ÷ 150 + 1 ÷ 510) − I × 8400 ÷ 43 × (1 ÷ 150 + 1 ÷ 510)

49075
    This is the solution of the equation.

    Convert the result to decimal form :
      I = 0.022191
