47 x y + 53 x y = 5684
( 47 + 53 ) x y = 5684
100 x y = 5684
y = 5684 : 100
y = 56,84
47 x y + 53 x y = 5684
( 47 + 53 ) x y = 5684
100 x y = 5684
y = 5684 : 100
y = 56.84
k mình nha!Cảm ơn bạn rất nhiều!
\(47\times y+53\times y=5684\)
\(y\left(47+53\right)=5684\)
\(y\times100=5684\)
\(y=5684:100\)
\(y=56,84\)
\(47\times y+53\times y=5684\)
\(\left(47+53\right)\times y=5684\)
\(100\times y=5684\)
\(y=5684:100\)
\(y=56,84\)
