(x)/(x + 3) = (2)/(5) \\2(x + 3) = 5x \\2(x) + 2(3) = 5x \\2x + 6 = 5x \\(6)/(3) = (3x)/(3) \\2 = x

X/x+3=2/5. We are going to do 3-2/5. The first thing you do is make 3 a fraction:
(3)/(1). Now the subtraction problem is
(3)/(1)- (2)/(5) Next we have to make common denominators for
(3)/(1) and
(2)/(5)
(3*5)/(1*5)= (15)/(5) \ and \ (2*1)/(5*1)= (2)/(5) Now we are going to subtract.
(15)/(5)- (2)/(5)= (13)/(5) So, X/x=
\boxed{ (13)/(5)} Hoped I helped. :)
