3) they will have the same solution because the first equation of system B is obtained by adding the first equation of system a
to 4 times the second equation of system a
4) The value of X for system a Will be equal to the value of Y for system b because the first equation of system b is obtained by adding -4 to the first equation of system a and the second equation are identical
4) The value of X for system a Will be equal to the value of Y for system b because the first equation of system b is obtained by adding -4 to the first equation of system a and the second equation are identical

The number of advance tickets sold is 25 and same day tickets sold is 30.
Data Given;
- Advance Ticket = $30
- Same-day Ticket = $25
- Total Ticket = $60
- Total Cost of Ticket = $1625
Let the number of advance ticket be represented by x
Let the number of same-day ticket be represented by y
From the system of equations above, we can easily pick any to start our calculation.
Using equation (i),
x + y = 60
x = 60 - y ...equation(iii)
Put equation (iii) into equation (ii)
Put the value of y into equation (i)
From the calculation above, the number of advance tickets sold is 25 and same-day tickets is 30.
