Question

\(y\cdot2+\frac{y}{2}=10\)

Answer 1

\(y\cdot2+\frac{y}{2}=10\)

\(y\cdot2+y:2=10\)

\(y\cdot2+y\cdot\frac{1}{2}=10\)

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

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

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

\(y=4\)

Answer 2

bằng 4

Answer 3

4 chắn chắn

k cho mình nha

Answer 4

y = 4 

4 x 2 + \(\frac{4}{2}\)= 10

Answer 5

Ta có

số đs = 4

hay

y = 4

nha bn

Answer 6

\(y\times2+\frac{y}{2}=10\)

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

\(\Leftrightarrow y\times\frac{5}{2}=10\Leftrightarrow y=10:\frac{5}{2}\Leftrightarrow y=4\)
