خطوات الحلّ

Represent the numbers with

x

:

First number : x

Consecutive number 1 : x + 1

Consecutive number 2 : x + 2

Consecutive number 3 : x + 3

A.T.Q.:

8 (x + \frac{1}{3}) = 40 + 10 (x + 3)

8 (x + \frac{1}{3}) = 40 + 10 (x + 3)

حلّ:

x = - \frac{101}{3}

x + 1 = - \frac{101}{3} + 1 = - \frac{98}{3}

x + 2 = - \frac{101}{3} + 2 = - \frac{95}{3}

x + 3 = - \frac{101}{3} + 3 = - \frac{92}{3}
