So first we need to know this:
Two negative signs make a positive
Two positives make a positive
One positive and one negative makes a negative.
So we can turn the equation to -4 -44 - - 1
2 minuses make plus
-4 -44 +1 = -48 +1 = -47
X-9 = -5x+ 9
x + 5x = 9 + 9
6x = 18
x = 3

Answer: 6 pieces
=======================================================
Explanation:
3/4 = 6/8 after multiplying both parts by 2
We have a ribbon that is 6/8 of an inch long. We want to cut it into 1/8 inch pieces. We can see there will be exactly 6 pieces
Note how 6*(1/8) = 6/8
Or we can think of it as "we have a ribbon that is 6 units long and we want to cut it into pieces that are 1 unit each, so we'll have 6 pieces total". Replace "unit" with "1/8 inch" and you'll have the same idea.
The chances of picking an even number (that is not odd) would be 1 out of 3
