PLEASE HELP IMMEDIATELY

Since l and m are parallel,

let the angle next to (6x+7) be 'a'

then a will be equal to (3x - 16) since 3x-16 and a are corresponding angles

Since the 2 angles make a linear pair,

6x + 7 + 3x -16 = 180

9x -9 = 180

x -1 = 20

x = 21

Since the angles 11y-32 and 6x + 7 are vertically opposite,

11y - 32 = 6x + 7

11y - 32 = 6(21) + 7

11y = 126 + 39

11y = 165

y = 15
