Question

Daca la "a" adun de trei ori "b", obtin 2,(5).Daca din "b" scad de trei ori "a",obtin 0,(3).Aflati a si b.  Heeeeeeeeeeeeelp mee noww !!!!

Answer 1

2,(5)=25-2/9=23/9
0,(3)=3/9 simplificam=1/3
a+3b=23/9          inmultim cu 3
-3a+b=1/3

3a+9b=23/3
-3a+b=1/3    se reduce a
10b=24/3
b=24/30 simplificam
b=4/5
a=23/9-3b
a=23/9-12/5
a=7/45
