....(3)

Let us solve the system of equations (3) and (1).

Multiply equation (1) by 3 to get

 ....(4)

Subtract equation (4) from equation (3) to get

Substitute the value of y in equation (1) to get the value of x

Thus, the first class ticket from Mumbai to Ahmedabad is Rs.210 and the reservation cost is Rs.6
