Answer 2

Hey there!

$\rm{\frac{5}{x} = \frac{7}{x + 2} }$

Solve:--

$\sf\rightarrow \: (7)(x) = (5)(x + 2)$

$\sf\rightarrow \: 7x = 5(x + 2)$

$\sf\rightarrow \: 7x = 5x + 10$

$\sf\rightarrow \: 7x - 5x= 5x + 10 - 5x$

$\sf\rightarrow \: 2x= 10$

$\sf\rightarrow \: \frac{ 2x}{2}= \frac{10 }{2}$

$\sf\rightarrow \: x= 5$

~Done~
