Answer 4

\(y.2+\frac{y}{2}=10\)

\(y.2+y.\frac{1}{2}=10\)

\(y\left(2+\frac{1}{2}\right)=10\)

\(y.\frac{5}{2}=10\)

\(y=10:\frac{5}{2}\)

\(y=4\)

Answer 5

\(\text{bn thik WINX nhỉ}\)\(???☺\)

Answer 6

y x 2 + y/2 = 10

y x 2 + y : 2 = 10

y x 2 + y x 1/2 = 10

y x ( 2 + 1/2 ) = 10

y x 5/2 = 10

=> y = 10 : 5/2

=> y = 4
