Question

-\(\left(x-\frac{2}{3}\right)x3=\frac{3}{4}\)

MK CẦN GẤP

Answer 1

-\(\left(x-\frac{2}{3}\right).3=\frac{3}{4}\)

-\(\left(x-\frac{2}{3}\right)=\frac{3}{4}:3\)

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

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

\(-x=\frac{11}{12}\)

\(=>x=-\frac{11}{12}\)

Answer 2

<br class="Apple-interchange-newline"><div id="inner-editor"></div>(x−23 ).3=34 

-(x−23 )=34 :3

-x−23 =14 

−x=14 +23 

−x=1112
