\(\frac{a+3b}{b}=\frac{a+b}{b}\Leftrightarrow a+3b=a+b\)
\(3b=b\Leftrightarrow b=0\)
\(\frac{a+3b}{b}=\frac{a+b}{b}\Leftrightarrow a+3b=a+b\)
\(3b=b\Leftrightarrow b=0\)
Tim a/b biet :a+3b/b=a+b/b
tim 2 so tu nhien a va b biet 2a-3b=100 va 15BCNN(a,b)+ 8UCLN(a,b)=1990
Tim a,b \(\in\)N biet 2a - 3b = 100 va 15[a,b] + 8(a,b) = 1550
tim a;b biet <2a.3b> = <10a.b>
tim 2 so nguyen duong a;b biet 2a-3b=100 va 15. BCNN(a;b)+8. UCLN(a;b)=1950
lam nhanh giup minh nha !! thank you verry!!
tim a,b,q thuoc N,biet
a:b=a
a:3b=8
a:13=q
ai giai truoc duoc like
1 Tim a biet .
a+b-c=18. voi b=10;c=-9
2a-3b+c=0
1-2b+c-3a=-9. voi b=-3 ;c=-7
Cac ban giup minh giai bai nay nhe cam on nhieu...
Bai 1:tim a,b biet a/b=4/5 va[a,b]=140
Bai 2:tim a,b biet a+b=42 va [a,b]=72
1. a) tim 2 so tu nhien a,b (a,b>0);biet (a,b)=9;[a,b]=54
b) tim 2 so tu nhien a,b (a,b>0);biet a+b=42; [a,b]=72
