    1. Why not just see which one works? 
Try 11. Is (3x13)+ 17 = 104? No
So, try the 23.
Is (3x25)+ 20 = 104? Yes

    2.  Let x represent his current age.  Solve for x.
x + 6 = 2x - 7
3.
n + d = c
n = c - d
    
x + 6 = 2x - 7
3.
n + d = c
n = c - d

    3.
5n + 10d = c
5n = c - 10d
n = c/5 - 2d
    
5n + 10d = c
5n = c - 10d
n = c/5 - 2d
