[ 1/1 Equation]
    Work: Find the solution of equation 300+387/(1+IRR)+193/(1+IRR)2+100/(1+IRR)3+150/(1+IRR)7 = 600/(1+IRR)4+600/(1+IRR)5+850/(1+IRR)6 .
    Question type: Equation
    Solution:Original question:
     300 + 387 ÷ (1 + I ) + 193 ÷ (1 + I ) × 2 + 100 ÷ (1 + I ) × 3 + 150 ÷ (1 + I ) × 7 = 600 ÷ (1 + I ) × 4 + 600 ÷ (1 + I ) × 5 + 850 ÷ (1 + I ) × 6
     Multiply both sides of the equation by:(1 + I )
     300(1 + I ) + 387 + 193 × 2 + 100 × 3 + 150 × 7 = 600 × 4 + 600 × 5 + 850 × 6
    Remove a bracket on the left of the equation::
     300 × 1 + 300 I + 387 + 193 × 2 + 100 × 3 + 150 × 7 = 600 × 4 + 600 × 5 + 850 × 6
    The equation is reduced to :
     300 + 300 I + 387 + 386 + 300 + 1050 = 2400 + 3000 + 5100
    The equation is reduced to :
     2423 + 300 I = 10500

    Transposition :
     300 I = 105002423

    Combine the items on the right of the equation:
     300 I = 8077

    The coefficient of the unknown number is reduced to 1 :
      I = 8077 ÷ 300
        = 8077 ×
1
300

    We obtained :
      I =
8077
300
    This is the solution of the equation.

    Convert the result to decimal form :
      I = 26.923333
