Answer:
x = 8
Step-by-step explanation:
Since the sum of all angles of a parallelogram is equal to 360 degrees, <Z + <Y is half of the parallelogram, and therefore <Z + <Y = 180 degrees.
16x-4 + 7x = 180, combine like terms
23x - 4 = 180, add 4 on both sides (isolate variable)
23x = 184, divide 23 on both sides
x = 8
X/2=8/9 | *2
x=16/9≈ 1,78
2. 1 $.........1,09 Euro
x$...........157 Euro
x=157*1/1,09≈144,04 $
The answer to this problem is x<-4
