\(x+\frac{7}{2}=\frac{11}{12}\)
\(x=\frac{11}{12}-\frac{42}{12}=-\frac{31}{12}\)
=> x + 7/2 = 11/6 x 1/2
=> x + 7/2 = 11/12
=> x = 11/12 - 7/2 = 11/12 -42 /12 = -31/12
\(x+\frac{7}{2}=\frac{11}{6}\div2\)
\(x+\frac{7}{2}=\frac{11}{6}\times\frac{1}{2}\)
\(x+\frac{7}{2}=\frac{11\times1}{6\times2}\)
\(x+\frac{7}{2}=\frac{11}{12}\)
\(x=\frac{11}{12}-\frac{7}{2}\)
\(x=\frac{11}{12}-\frac{42}{12}\)
\(x=\frac{11-42}{12}=-\frac{31}{12}\)
x+7/2=11/6:2
=> x+7/2=11/12
=> x =11/12-7/12
=> x =1/3
Ai k mik mik k lại. chúc các bạn thi tốt
\(x+\frac{7}{2}=\frac{11}{12}\Rightarrow x=\frac{11}{12}-\frac{7}{2}\Rightarrow x=\frac{-31}{12}\)
