tính giúp mình nhé trước 1 giờ ngày hôm nay

Answer 1

\(\dfrac{2}{3}x+\dfrac{1}{4}=\dfrac{7}{12}\)

\(\dfrac{2}{3}x=\dfrac{1}{3}\)

\(x=\dfrac{1}{3}:\dfrac{2}{3}\)

\(x=\dfrac{1}{2}\)

Answer 2

<=> \(\dfrac{2}{3}x\) = \(\dfrac{1}{3}\)

<=> x = \(\dfrac{1}{2}\)

Answer 3

\(\dfrac{2}{3}x+\dfrac{1}{4}=\dfrac{7}{12}\)

\(\dfrac{2}{3}x=\dfrac{7}{12}-\dfrac{1}{4}\)

\(\dfrac{2}{3}x=\dfrac{1}{3}\)

\(x=\dfrac{1}{3}:\dfrac{2}{3}\)

\(x=\dfrac{1}{2}\)
