It's important that you learn to take the 'given' facts and turn them into an equation. In this way, you will truly learn (which means that you'll move toward self reliance).
 
Let second number be x; then the first number is (3/10)x.  
 
Thus, x + 0.3x = 16.  Solve for x.

It' may seem minor, but it is a little clearer to translate:
     "The sum of two numbers is 26" into
     first number   +   second number   =  26
          x              +     (3/10)x             = 26
                     (13/10)x  =  26
                            . . .
 
... and not introduce decimals.

. . .   ah-ha!   It even confused me:
 
     first number   +   second number   =  26
          (3/10)x     +     x             = 26
                     (13/10)x  =  26
