Respuesta :
The four parts are 15, 9, 36 and 4
64 is split into 4 parts
3 is added to the first part
- a + 3
3 is subtracted from the second part
- a - 3
the third part is multiplied by 3
- 3a
the fourth part is divided by 3
- a / 3
Therefore,
(a + 3) + (a - 3) + (3a) + (a / 3) = 64
multiply through by 3 to eliminate the fraction
(3a + 9) + (3a - 9) + 9a + a = 192
16a = 192
a = 192 / 16
a = 12
Therefore,
The four parts are
a + 3 = 12 + 3 = 15
a - 3 = 12 - 3 = 9
3a = 3 × 12 = 36
a / 3 = 12 / 3 = 4
Reverse it you will notice all 4 parts are equal . For example
15 - 3 = 12
9 + 3 = 12
36 / 3 = 12
4 × 3 = 12
