When you solve a proportion, your first step should be to cross-multiply.

[tex] \frac{2x}{5} [/tex] = [tex] \frac{x + 3}{3} [/tex]

When you cross-multiply, you should get this equation:

(2x)(3) = (x + 3)(5)

Now, solve it using algebra.

(2x)(3) = (x + 3)(5)       Multiply
       6x = 5x + 15         Subtract 5x from both sides
         x = 15

The value of x is 15.
