Hey there!


\rm{(5)/(x) = (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 \: ( 2x)/(2)= (10 )/(2)


\sf\rightarrow \: x= 5

~Done~
