Question

$\frac{x - 2 }{x - 3} = \frac{7}{5}$
​

Answer 1

$\frac{x-2}{x-3}=\frac{7}{5} \\ \\ 5\cdot (x-2)=7\cdot (x-3) \\ \\ 5x-10=7x-21 \\ \\ 5x-7x=-21+10 \\ \\ -2x=-11 \\ \\ 2x=11 \\ \\ x=\frac{11}{2} =5\frac{1}{2}=5,5$

Answer 2

Ответ:

$\frac{x - 2}{x - 3} = \frac{7}{5} \\ 5(x - 2) = 7(x - 3) \\ 5x - 10 = 7x - 21 \\ 5x - 7x = - 21 + 10 \\ - 2x = - 11 \\ x = 5.5$
