Question

Afla fiecare litera:
a+b+c= 692
a+x=126
b+x=247
c+x=394

VA ROG REPEDE!!!! DAU COROANĂ!

Answer 1

a + b + c = 692
a + x = 126
b + x = 247
c + x = 394

a + x = 126
b + x = 247
c + x = 394
-----------------
a + x + b + x + c + x = 126 + 247 + 394
a + x + b + x + c + x = 373 + 394
a + x + b + x + c + x = 767
a + b + c + x + x + x = 767
a + b + c = 692
=> 692 + 3x = 767 | - 692
=> 3x = 75 | : 3
=> x = 25

a + x = 126
x = 25
=> a + 25 = 126 | - 25
=> a = 101

b + x = 247
x = 25
=> b + 25 = 247 | - 25
=> b = 222

c + x = 394
x = 25
=> c + 25 = 394 | - 25
=> c = 369

Succes!

Answer 2

a+b+c=692
a+x=126
b+x=247
c+x=394
a+b+c+a+x+b+x+c+x=692+126+247+394
2a+2b+2c+3x=1459
a+b+c=692
a+b+c+3x=767
3x=767-692
3x=75
x=75:3
x=25
a=126-25
a=101
b=247-25
b=222
c=394-25
c=369
R=101, 222, 369.
