Răspuns :
a + b + c = 7450
a = 9
b = 9 x 4 = 36
9 + 36 + c = 7450
45 + c = 7450
c = 7450 = 45 = 7405
c = 7405
a = 9
b = 9 x 4 = 36
9 + 36 + c = 7450
45 + c = 7450
c = 7450 = 45 = 7405
c = 7405
a+b+c=7450
a=9
b=4 x a => b=4 x 9=36
Deci
9+36+c=7450
45+c=7450
c=7450-45
c=7405
a=9
b=4 x a => b=4 x 9=36
