Question

x - 1/2 + 2/3 = 3/4. Tìm x

Answer 1

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

Answer 2

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

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

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

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

\(x=\dfrac{7}{12}\)

Answer 3

X =7/12

Answer 4

x−1/2=3/4−2/3

x=1/12+1/2
