a=8 and b=6

Step-by-step explanation:

First you need to make common denominator.

Multiply 3 over 5x by (x+2) on both top and bottom to get 3x+6 over 5x(x+2).

Then, multiply 1 over x+2 by 5x on top and bottom to get 5x over 5x(x+2)

And then add the numerators.

3x+6+5x

you get 8x+6

ax+b correspond to 8x+6

so a=8 and b=6

true? is that what you're asking or do you mean something else?
