Answer 1

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~
