Nine more than four times a number is the same as one less than twice the number. find the number?

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

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
