Question

-2/3-1/3(2x-5)=3/2

Answer 1

li-ke cho mình nhé bnpé chibi hay thắc mắc

Answer 2

\(-\frac{2}{3}-\frac{1}{3}\left(2x-5\right)=\frac{3}{2}\)

\(\frac{1}{3}\left(2x-5\right)=-\frac{2}{3}-\frac{3}{2}=-\frac{4}{6}-\frac{9}{6}=-\frac{13}{6}\)

\(2x-5=-\frac{13}{6}:\frac{1}{3}=-\frac{13}{6}.3=-\frac{13}{2}\)

\(2x=-\frac{13}{2}+5=-\frac{3}{2}\)

\(x=-\frac{3}{2}:2=-\frac{3}{2}.\frac{1}{2}=-\frac{3}{4}\)
