      (Show Source): 
You can put this solution on YOUR website! Let A be the larger number, and B be the smaller. A = 3B - 7
 A + B = 37
 substitute the known value of A from the first equation into the second.
 (3B-7) + B = 37
 Add
 4B-7 = 37
 Add 7 to each side
 4B = 44
 Divide each side by 4
 B = 11
 If B is 11, then A is 37-11 = 26.
 .
 Let's put the values into the first equation to prove.
 26 = (3*11)-7
 26 = 33 - 7
 26 = 26
 Success!
