## Solve Algebra Linear Equations using Backtracking

I received a picture puzzle in WhatsApp. I will explain here how I solved that using programming. I used Backtracking concept. Received picture puzzle below puzzle is simple algebra concept. If you have paper and pencile then it can be solved easily. But I just wanted to use some programming concept. Algebra notation of the puzzle just fill the empty circle with some letters (a,b,c,d,e) Left to right a - b = 5 c + 1 = d 12 - e = 10 Top to bottom...
