At last Friday's football game there were a total of 413 fans in attendance, including students and non-students. Let x represent the number of students and y represent the number of non-students. Which of the statements could represent the number of fans? Select all that apply.

• $x+y=413$

• $235\ and\ 178$

• $x=y-413$

• $y=-x+413$

• $143\ and\ 230$

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Solve for y:
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16
