Yes, two linear equations have a common solution if the lines represnted by them are intersecting.
 
Note: A linear equation in x and y always represents a straight line.
Two straight lines are either parallel or intersecting.
Thus only intersecting lines have a common solution.
 
Now consider 3 linear equations in x and y.
We say they are consistent, if they have a common solution.
In geometry we say the lines are concurrent.

Data given below is related to daily routine [study time (in hours), entertainment time (in hours) and rest time (in hours)] of three students A, B and C.    Daily routine (24 hours) = Study time + Entertainment time + Rest time   A's study time is 1 hour less than B's study time and A's rest time is 7 hours more than his entertainment time. Ratio of A's entertainment time to B's entertainment time is 1: 2. Average of study time of A, B and C is 6 hours. Average of rest time of A and B is 9 hours. Ratio of C's entertainment time to his rest time is 4: 3.   If B's study and entertainment time is m% more than C's study and entertainment time together, then find that B's study and entertainment time together is what percent more than A's study and entertainment time together?
