Question

tìm x

\(\dfrac{x-12}{4}=\dfrac{1}{2}\)

Answer 1

\(\dfrac{x-12}{4}=\dfrac{1}{2}\)

\((x-12).2=4\)

\(x-12=2\)

\(x=14\)

Vậy \(x=14\)

Answer 2

Vì \(\dfrac{x-12}{4}\) = \(\dfrac{1}{2}\)

=> ( x -12).2 = 4

x - 12 = 4:2

x -12 = 2

=> x = 2 + 12

x = 14

Vậy x = 14

Answer 3

\(\dfrac{x-12}{4}=\dfrac{1}{2}\)

\(\dfrac{x-12}{4}=\dfrac{2}{4}\)

\(\Rightarrow\) x - 12 = 2

x = 2 + 12

x = 14

Answer 4

\(\Rightarrow\) X-12x2 = 4x1

X-12x2 = 4

X-12 = 4 / 2

X-12 = 2

X =2+12

X =14

Answer 5

Lời giải:

\(\dfrac{x-12}{4}=\dfrac{1}{2}\)

\(\Rightarrow2\left(x-12\right)=4.1\)

\(\Rightarrow2\left(x-12\right)=4\)

\(\Rightarrow x-12=2\)

\(\Rightarrow x=14\)
