Solve for x. Each figure is a parallelogram

1....4x-5=19
X=24/4
X=6
2......the answer is 1
3......X=16-6=10
4.....360-260=100
now,8x-6=50
8x=56
X=7
Answer:
4) A) 6
5) C) 1
6) D) 10
7) B) 7
Step-by-step explanation:
4) 4x-5 = 19
4x = 24
x = 6
5) 20x = 20
x = 1
6) x+ 6 = 16
x = 10
7) 180 - 130 = 50 because they are supplementary angles
8x - 6 = 50
8x = 56
x = 7
