Question

x-8=50%.x

giải hộ mình đang cần gấp

Answer 1

          \(x-8=50\%\cdot x\)

\(\Leftrightarrow\)\(50\%\cdot x=8\)

            \(\frac{1}{2}x=8\)

              \(x=8\text{ x }2\)

              \(x=16\)

Answer 2

x - 8 = 1/2x 

=> x - 1/2x = 8 

=> 1/2x = 8 

=> x = 8 : 1/2 

=> x = 8.2 

=> x = 16 

Vậy x = 16 

Answer 3

x-8=50%.x

<=>x-50%x=8

<=>50%x=8

<=>x=8:50%

<=>x=16

vậy x=16

Answer 4

x-8=50%.x

x-8=50/100.x

x-8=1/2.x

x-1/2.x=8

x.(1-1/2)=8

x.1/2=8

x=8:1/2

x=8.2

x=16

Vậy x =16 

Answer 5

\(x-8=50\%\cdot x\)

\(\Leftrightarrow x-8=\frac{50}{100}\cdot x\)

\(\Leftrightarrow x-8=\frac{x}{2}\)

\(\Leftrightarrow\left(x-8\right)\cdot2=x\)

\(\Leftrightarrow2x-16=x\)

\(\Leftrightarrow2x-x=16\)

\(\Rightarrow x=16\)

Vậy x=16

Answer 6

\(x-8=50\%.x\)

\(\Leftrightarrow50\%.x=8\)

\(\frac{1}{2}.x=8\)

\(x=8:\frac{1}{2}\)

\(x=8.2\)

\(x=16\)

Vậy...........................

Answer 7

x-8=50%.x

x-8=1/2.x

x-1/2.x=8

x.(1-1/2)=8

x.1/2=8

x=8:1/2

x=8.2

x=16

Answer 8

\(x-8=50\%\times x\)

\(\Rightarrow x-8=\frac{50}{100}\times x\)

\(\Rightarrow x-8=\frac{1}{2}\times x\)

\(\Rightarrow x-\frac{1}{2}\times x=8\)

\(\Rightarrow x\times\left(1-\frac{1}{2}\right)=8\)

\(\Rightarrow x\times\frac{1}{2}=8\)

\(\Rightarrow x=8\div\frac{1}{2}\)

\(\Rightarrow x=16\)

Vậy x = 16
