The ratio of boys to girls in a group is 7:1. If there are 36 more boys than girls, work out how many boys there are. I need the answer no

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

3x + 4y = 5 x- 3y = -7 solve by substitution
