Question

a-b
= 18 275
b-c
= 93 104
c-d = 3 608
d = 42 511
a + b + C + d = ?​

Answer 1

Răspuns:

c-d=3608

d=52511

c-42511=3608

c=42511+3608

c=46119

b-46119=93104

b=46119+93104

b=139223

a-139223=18275

a=139223+19275

a=158498

Answer 2

Explicație pas cu pas:

d=42.511.

c-42.511=3.608

c=42.511+3.608=56.119

b-56.119=93.104

b=93.104+56.119=149.223

a-149.223=18.275

a=149.223+18.275=167.498

42.511+ 98.620+ 247.843+

56.119 149.223 167.498
