)(1 + a )
    Remove the bracket on the right of the equation:
     Right side of the equation = 240 ×

(1 + a )
                                               = 24(1 + a ) + 144(1 + a ) +
72

(1 + a )
                                               = 24 × 1 + 24 a + 144(1 + a ) +
72

(1 + a )
                                               = 24 + 24 a + 144(1 + a ) +
72

(1 + a )
                                               = 24 + 24 a + 144 × 1 + 144 a +
72
5
(1 + a )
                                               = 24 + 24 a + 144 + 144 a +
72

(1 + a )
                                               = 168 + 168 a +
72

    The equation is transformed into :
     240 =
912
5
+
912
5
a

    Transposition :
      -
912
5
a =
912
5
240

    Combine the items on the right of the equation:
      -
912
5
a = -
288
5

    By shifting the terms and changing the symbols on toth sides of the equation, we obtain :
     
288
5
=
912
5
a

    If the left side of the equation is equal to the right side, then the right side must also be equal to the left side, that is :
     
912
5
a =
288
5

    The coefficient of the unknown number is reduced to 1 :
      a =
288
5
÷
912
5
        =

19

    We obtained :
      a =
6
19
    This is the solution of the equation.

    Convert the result to decimal form :
      a = 0.315789
