Câu 5: 

a) \(\left|3-2x\right|=\dfrac{1}{2}\)

Khi \(x\ge0\), ta có

\(3-2x=\dfrac{1}{2}\)

\(2x=\dfrac{5}{2}\)

\(x=\dfrac{5}{4}\)

Khi \(x< 0\), ta có

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

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

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

\(x=\dfrac{7}{4}\)

b) \(\dfrac{x-1}{4}=\dfrac{10}{8}\)

\(\dfrac{x-1}{4}=\dfrac{5}{4}\)

\(x-1=5\)

\(x=6\)

Câu 6: 

Áp dụng tính chất của dãy tỉ số bằng nhau, ta được:

\(\dfrac{a}{b}=\dfrac{c}{d}=\dfrac{a+c}{b+d}=\dfrac{a-c}{b-d}\)

hay \(\dfrac{a+c}{b+d}=\dfrac{a-c}{b-d}\)

Bài 6 đề sai nhé.

\(\widehat{ABz}\) hay \(\widehat{ABx}=42^o\)
