386.62+386.a=38600
386.(62+a)=38600
62+a=100
a=38
\(386\times62+386\times a\)\(=38600\)
\(\Leftrightarrow386\times\left(62+a\right)=38600\)
\(\Leftrightarrow62+a=38600:386\)
\(\Leftrightarrow62+a=100\)
\(\Rightarrow a=100-62\)
\(a=38\)
386 x 62 + 386 x a = 38600
( 62 + a ) x 386 = 38600
62 + a = 38600 : 386
62 + a = 100
a = 100 - 62
a = 38
Vậy a = 38
~ Chúc bạn hok tốt ~
386x62+386xa=38600
(62+a)x386=38600
(62+a)=38600:386
(62-a)=100
a=100-62
a=38
hok tốt
