X= number of student tickets
Y= number of on student tickets
x+y=311
0.50x + 1.50y = 385.50
Solve x in 1st equation
X+y=311
X= -y + 311
Now substitute x into second equation to solve for y
0.50(-y+311)+ 1.50y = 385.50
-0.50y+311.50+1.50y=385.50
Y+311.50=385.50
Y= 385.50-311.50
Y= 74
Now substitute y answer to first equation to find x
X+y=311
X+ 74=311
X= 311-74
X= 237
So 237 students tickets and 74 non students tickets
As you know, to get the inverse of any expression, we start off by switching the variables about and then solving for "y",
