What is the system of equations?
A system of equations, also known as an equation system or a set of simultaneous equations, is a finite set of equations for which common solutions are sought.
Here, we
Let
x = the number of adult tickets sold
y = the number of senior tickets sold
483 people paid admission => a total of 483 tickets were sold and
x + y = 483
the total receipts were $7548
24x + 12y = 7548
by solving the system of equations
x + y = 483....(1)
24x + 12y = 7548....(2)
From equation (1), we get
x = 483-y....(3)
Now, we put the value of x in equation (2) and we get
24(483 - y) +12y = 7548
11592 - 24y + 12y = 7548
12y = 4044
y = 337
Now, we put the value of y in equation (1) and we get
x = 483 - 337
x = 146
Hence, 337 were senior citizens.
