Question

7 phần 2 trừ 3 phần 2 x = 11 phần 2

Answer 1

\(\dfrac{7}{2} - \dfrac{3}{2}x = \dfrac{11}{2}\)

\( \dfrac{3}{2}x = \dfrac{7}{2} - \dfrac{11}{2}\)

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

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

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

\(x = -2 . \dfrac{2}{3} \)

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

Vậy \(x = \dfrac{-4}{3} \)

Answer 2

\(\dfrac{7}{2}-\dfrac{3}{2}x=\dfrac{11}{2}\\ \dfrac{3}{2}x=\dfrac{7}{2}-\dfrac{11}{2}\\ \dfrac{3}{2}x=-2\\ x=-2:\dfrac{3}{2}\\ x=\dfrac{-4}{3}\)
