find the value of y. (3y+1) (8x-61) (6x-13)

Answer:
y = 16
Step-by-step explanation:
you can set 6x - 13 and 8x - 61 equal to each other because they are Alternate-Exterior angles and are congruent; this will give you the value of 'x'
6x - 13 = 8x - 61
-13 = 2x - 61
2x = 48
x = 24
3y + 1 + 8x - 61 = 180 (they form a straight line)
substitute 24 for 'x'
3y + 1 + 8(24) - 61 = 180
3y + 132 = 180
3y = 48
y = 16
