Question

\(\frac{x-1}{x+5}=\frac{6}{7}\)                            tính hộ mik

Answer 1

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

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

7x - 7 = 6x + 30

7x - 6x = 30 + 7

x = 37

Answer 2

<=> (x - 1) . 7 = (x + 5) . 6

<=> 7x - 7 = 6x + 30

<=> 7x - 6x = 7 + 30

<=> x = 37

Answer 3

ĐKXĐ: x khác 5

\(\Rightarrow7\left(x-1\right)=6\left(x+5\right)\)

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

\(\Rightarrow x=37\)
