10. robby has 16 tickets
that total $98. if adults
cost $8, and kids $5.50,
write the system.
let x = # of adult tickets and y = # of kid tickets
11. combine the equations:
x + y = -3
-x + y = 1
now solve for y
12. if y = 3 - x, then use substitution
to find x and y when x - 2y = 0 x=
y=
13. if x= -1,
find y when
3x - y = -15
now, solve for y:
y=
