Question

giúp mình vơi,mình cần gấp

Answer 1

Câu 1: \(-7/6+15/6=8/6=4/3\)

Câu 2: \(x=7/12-1/6=>x=7/12-2/12=>x=5/12\) nhé =) 

Answer 2

câu 1

\(\dfrac{-7}{6}+\dfrac{15}{6}=\dfrac{-7+15}{6}=\dfrac{8}{6}=\dfrac{4}{3}\)

câu 2

\(x+\dfrac{1}{6}=\dfrac{7}{12}\)

\(x=\dfrac{7}{12}-\dfrac{1}{6}\)

\(x=\dfrac{7}{12}-\dfrac{2}{12}=\dfrac{7-2}{12}\)

\(x=\dfrac{5}{12}\)
