Ai zỗi m à trả lời!!?

He has read that novel many times before

When you come back, he has already bought the house

Từ mom nhé

mother nha bạn

a = \(\frac{4a-5b}{6a+b}\) (1) và \(\frac{a}{b}=\frac23\)

Giải:

\(\frac{a}{b}=\frac23\) suy ra: a = \(\frac{2b}{3}\)

Thay a = 2b/3 vào (1) ta có:

2b/3 = \(\frac{\frac{4.2b}{3}-5b}{\frac{6.2b}{3}+b}\) = \(\frac{b.\left(\frac83-5\right)}{b.\left(4+1\right)}\) = (\(\frac83-\frac{15}{3}):5\) = - \(\frac73\times\frac15\) = - 7/15

b = - 7/15 : (2/3) = - \(\frac{7}{10}\)

a = 2b/3 = (-7/10) x (2/3) = -7/15

Vậy a = - 7/15; b = - 7/10

ba​=32​ suy ra: a = \(\frac{2 b}{3}\)

Thay a = 2b/3 vào (1) ta có:

2b/3 = \(\frac{\frac{4.2 b}{3} - 5 b}{\frac{6.2 b}{3} + b}\) = \(\frac{b . \left(\right. \frac{8}{3} - 5 \left.\right)}{b . \left(\right. 4 + 1 \left.\right)}\) = (\(\frac{8}{3} - \frac{15}{3} \left.\right) : 5\) = - \(\frac{7}{3} \times \frac{1}{5}\) = - 7/15

b = - 7/15 : (2/3) = - \(\frac{7}{10}\)

a = 2b/3 = (-7/10) x (2/3) = -7/15

Vậy a = - 7/15; b = - 7/10

ko bt

Đang nói tiếng anh rồi còn j :)

hay

\(\frac{208}{384}\) = a - \(\frac{2}{24}\)

\(\frac{13}{24}\) = a - \(\) \(\frac{2}{24}\)

a = \(\frac{13}{24}+\frac{2}{24}\)

a = \(\frac{15}{24}\)

a = \(\frac58\)
