Question

Determinati cifrele x si y in fiecare din situatiile: x35 barat+1ybarat=448
Nu stiu daca este corect:

x35 barat = x*10+35
1ybarat = 1*10+y
x*10+35+ 1*10+y = 448
10*x+45 +y =448
10x+y=403!!!!!!

Answer 1

X35barat are 3 cifre=X×100+3×10+5
100X+35+10+Y=448
100X+Y=448-45
100X+Y=403
100X+Y=400+3
X=4
Y=3
