Question

giúp em bài này nè ạ

Answer 1

a: =>x+5/2=-4/3

hay x=-23/6

b: =>8/3-x=11/4-4/4=7/4

hay x=8/3-7/4=11/12

c: =>1-x=-27/6-5/6=-32/6=-16/3

=>x=1+16/3=19/3

d: =>x-7/4=11/12+12/12=23/12

=>x=7/4+23/12=21/12+23/12=44/12=22/6=11/3

Answer 2

\(a,x+\dfrac{5}{2}=\dfrac{-4}{3}\Leftrightarrow x=\dfrac{-4}{3}-\dfrac{5}{2}=\dfrac{-23}{6}\)

\(b,\dfrac{8}{3}-x=\dfrac{7}{4}\Leftrightarrow x=\dfrac{8}{3}-\dfrac{7}{4}=\dfrac{11}{12}\)

\(c,1-x=\dfrac{-16}{3}\Leftrightarrow x=1+\dfrac{16}{3}=\dfrac{19}{3}\)

\(d,\dfrac{-7}{4}+x=\dfrac{23}{12}\Leftrightarrow x=\dfrac{23}{12}+\dfrac{7}{4}=\dfrac{11}{3}\)
