Answer:

#1

6 × n + 15 = -42

6n + 15 = -42

6n = -42 - 15

6n = -57

n = -57/6

n = -19/3

#2

b + 3/2b + b + 45 + 2b - 5 + 90 = 540

b + 1.5b + b + 45 + 2b - 5 + 90 = 540

5.5b + 130 = 540

5.5b = 540 - 130

5.5b = 410

b = 410/5.5

b = 74.5

Angles are

b = 74.5

1.5(74.5) = 111.75

74.5 + 45 = 119.5

2(74.5) - 5 = 144
