Reading as:-
2 / (x + 3) = 5 / x
2x = 5x + 15
3x = - 15
x = - 5
However if question is:-
(2 / x) + 3 = 5 / x
2 + 3x = 5
3x = 3
x = 1
Take your pick!

2/x + 3 = 5/x
Multiply both sides by x.
2 + 3x = 5
3x = 3
x = 1

Mult. both sides of the equation by x to cancel out the x terms that are in denominators:
(2/x + 3)x = (5/x)x
2 + 3x = 5
Subtract 2 from both sides to isolate the x term. Divide that equation by the coefficient of x, and you have your solution.
