3x/5+2=8  

Let's multiply through by 5 on both sides to "clear" the fraction

5(3x/5) + 5(2) = 5(8)

3x + 10  = 40      Subtract 10 from both sides

3x = 30               Divide both sides by 3

x = 10

And that's it.....you should check to see that this answer is correct by substituting it back into the original equation.
