multiply the 2 parts by a :
5+3a = 3-2a
So
5a = -2
a=-2/5=-0.4

If you mean to ask your problem as written,
5 / a + 3 = 3 / a - 2 yields a = (-2 / 5).
If you meant the problem to be
5 / (a + 3) = 3 / (a - 2),
then be sure to use parentheses to show the proper order of operations when writing your problem on one line.
5 / (a + 3) = 3 / (a - 2) can be solved by cross-multiplying, like any proportion.
5(a - 2) = 3(a + 3) [Distribute.]
5a - 10 = 3a + 9 [Add (-3a + 10) to both sides to isolate the variable.]
2a = 19
a = 19 / 2 = 9 1/2 = 9.5

If you meant: 5 / (a +3) = 3 / (a - 2), then do it like this.
Multiply both sides by [(a + 3)(a - 2)].
5(a - 2) = 3(a + 3)
5a - 10 = 3a + 9
2a = 19
a = 19/2 or 9.5
If you meant what you typed, which is 5/a + 3 = 3/a - 2, then do this.
Add 2 to both sides.
5/a + 5 = 3/a
Now, multiply everything by "a".
5 + 5a = 3
5a = -2
a = -2/5 or -.4

Multiply both sides of the equation by to get rid of the denominator a. You then get the equation 5+3a=3-2a. Subtract 5 from both sides to get 3a-=-2-2a. Add 2a to both sides to get 5a=-2. solve for a by dividing both sides by 5. answer: a=-2/5

(5/(a + 3)) = (3/(a - 2))
cross multiply
5(a - 2) = 3(a + 3)
5a - 10 = 3a + 9
2a = 19
a = (19/2)

5/a+3=3/a-2
take same varibles on same side
5/a-3/a=-2-3=-5
2/a=-5
a=-(2/5)

5(a-2)=3(a+3)
2a=19
a=9.5
