x = adult tickets
y = student tickets
x + y = 273
2x = y
In order to solve this, use substitution:
x + 2x = 273
3x = 273 (divide by 3 on both sides)
x = 91 adult tickets
If you want to check your answer, plug in your answer into the second equation and then use both answers for the first equation:
2x = y
2(91) = y
y = 182 student tickets
x + y = 273
91 + 182 = 273
273 = 273 (If both sides are the same value, this means your answer is correct.)
Best of luck, friend.
