Yes they are the same.
When you add like terms:
8x - 14 = 8x + 5 - 19
8x - 14 = 8x - 14
The two sides equal the same thing.
1. You could add 16 + 35 (which equals 51), then add 51 + 24 (equals 75) then add 14 (equals 89)
2. Add 16 + 35 (equals 51), add 24 + 14 (equals 38) then add 51+38 (Equals 89)
5x-y=-8 | subtract 5x from both sides.
-y = -5x - 8 | divide both sides by -1
y = 5x + 8 Done.
It is 99.5% because 99.5% is in the middle of 99% and 100%
hope I helped!!!
