Hey. Why are you so worried. Here is the answer. There is a very small problem.It is that the decimal point is not added.
47, 57, 67, 77 are the numbers.
Create formulas!
x=number of adult tickets
y=number of student tickets
x+y=644 <em>total sold</em>
56+y=x <em>student was 56 less than adult</em>
Perform substitution
(56+y)+y=644
56+2y=644
2y=588
y=294
Substitute y into the formula we created
x+294=644
x=350
350 adult tickets were sold.
