\(\frac{7}{4}-x\times\frac{5}{6}=\frac{1}{2}+\frac{1}{3}\)
\(\frac{7}{4}-x\times\frac{5}{6}=\frac{5}{6}\)
\(x\times\frac{5}{6}=\frac{7}{4}-\frac{5}{6}\)
\(x\times\frac{5}{6}=\frac{11}{12}\)
\(x=\frac{11}{12}\div\frac{5}{6}\)
\(x=\frac{11}{10}\)
k mk nha Vũ Nhật Minh
7/4-Xx5/6=1/2+1/3
=> 7/4-x.5/6=5/6
=> x.5/6=7/4-5/6=11/12
=>x=11/12:5/6=11/10
bấm **** nha
