Question

x*2+x:2=10

Answer 1

x . 2 = 10 - x : 2

2     =   10 - x : 1

2     = 10 - x

x     = 10 - 2

x     = 8

Answer 2

x.2 + x:2 = 10

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

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

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

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

\(x=10.\frac{2}{5}=4\)

Answer 3

x*2+x:2=10

=>x*2+x*(1/2)=10

=>x*(2+1/2)=10

=>x*5/2=10

=>x=10:5/2

=>x=10*2/5

=>x=4

Answer 4

\(x.2+x:2=10\)

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

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

\(x.\frac{3}{2}=10\)

\(x=10:\frac{3}{2}\)

Answer 5

sorry mình nhầm

\(x.2+x:2=10\)

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

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

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

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

\(x=4\)
