\(a,X+\dfrac{3}{4}=\dfrac{7}{3}\\ X=\dfrac{7}{3}-\dfrac{3}{4}\\ X=\dfrac{7.4-3.3}{3.4}=\dfrac{28-9}{12}=\dfrac{19}{12}\\ ---\\ b,X+\dfrac{13}{24}=\dfrac{-19}{16}\\ X=\dfrac{-19}{16}-\dfrac{13}{24}\\ X=\dfrac{-19.3-13.2}{48}=\dfrac{-57-26}{48}=\dfrac{-83}{48}\\ ---\\ c,X-\dfrac{-11}{18}=\dfrac{-37}{27}\\ X+\dfrac{11}{18}=\dfrac{-37}{27}\\ X=\dfrac{-37}{27}-\dfrac{11}{18}=\dfrac{-37.2-11.3}{54}=\dfrac{-74-33}{54}=\dfrac{-107}{54}\\ ----\\ d,X-\dfrac{13}{18}=\dfrac{-19}{12}\\ X=\dfrac{-19}{12}+\dfrac{13}{18}\\ X=\dfrac{-19.3+13.2}{36}=\dfrac{-57+26}{36}=\dfrac{-31}{36}\)
\(a.x+\dfrac{3}{4}=\dfrac{7}{3}\)
\(x=\dfrac{7}{3}-\dfrac{3}{4}\)
\(x=\dfrac{19}{12}\)
\(b.x+\dfrac{13}{24}=\dfrac{-19}{16}\)
\(x=\dfrac{-19}{16}-\dfrac{13}{24}\)
\(x=\dfrac{-83}{48}\)
\(c.x-\dfrac{-11}{18}=-\dfrac{37}{27}\)
\(x=\dfrac{-37}{27}+\dfrac{-11}{18}\)
\(x=\dfrac{-107}{54}\)
\(d.x-\dfrac{13}{18}=\dfrac{-19}{12}\)
\(x=\dfrac{-19}{12}+\dfrac{13}{18}\)
\(x=-\dfrac{31}{36}\)
