I need help on this and the first person who answer correctly gets a BRANLIST​

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

X+ y = 5 ; x - y =3 solve using linear combination

What function has a range {yly< 5}? question on picture above^
