Question

Answer 1

a: Ta có: \(\dfrac{x-1}{x+5}=\dfrac{6}{7}\)

\(\Leftrightarrow7x-7=6x+30\)

hay x=37

Answer 2

\(\dfrac{x-1}{x+5}=\dfrac{6}{7}\)

\(\Rightarrow7x-7=6x+30\)

\(\Rightarrow x=37\)

Answer 3

\(\dfrac{x-1}{x+5}=\dfrac{6}{7}\Leftrightarrow6x+30=7x-7\Leftrightarrow x=37\)

Answer 4

(x-1)7=(x+5)6

7x-7=6x+30

7x-6x=30+7

x=37

Answer 5

\(a) \dfrac{x-1}{x+5} <=>7x - 7 = 6x + 30 => x=....\)
