Question

Answer 1

=>|0,5x+0,25|=-1/2+1+2/3=7/6

=>1/2x+1/4=7/6 hoặc 1/2x+1/4=-7/6

=>1/2x=11/12 hoặc 1/2x=-17/12

=>x=11/6 hoặc x=-17/6

Answer 2

|\(\dfrac{1}{2}\)x + \(\dfrac{1}{4}\)| - \(\dfrac{5}{3}\) = \(\dfrac{-1}{2}\)

\(\dfrac{1}{2}\)x + \(\dfrac{1}{4}\)         = \(\dfrac{-1}{2}\) + \(\dfrac{5}{3}\)

\(\dfrac{1}{2}\)x + \(\dfrac{1}{4}\)         = \(\dfrac{7}{6}\)

\(\dfrac{1}{2}\)x                = \(\dfrac{7}{6}\) - \(\dfrac{1}{4}\)

\(\dfrac{1}{2}\)x                = \(\dfrac{11}{12}\)

   x                = \(\dfrac{11}{12}\) : \(\dfrac{1}{2}\)

   x                = \(\dfrac{11}{6}\)
