2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0

If all the variables are the same, you just add (algebraically add) the numbers. For example: 3a + 4a = 7a 2a - 10a = -8a
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3

9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
7a+a=8a
-8
2a - 4y = 3a - 8a - 5y 7a = -ya = -(y/7)
a2 + 7a - 8a2 = 6a7 ∴ a2 + 7a - 8a2- 6a7 = 0 ∴ a + 7 - 8a - 6a6 = 0 ∴ 7 - 7a - 6a6 = 0 ∴ 6a6 + 7a - 7 = 0
The answer would be 8a because... 7a is the same as 7 times a a is the same as 1a. So 7+1=8 and just add on the a
Groups 6A and 7A are typically classified as the "chalcogens" and "halogens," respectively. Group 8A is known as the "noble gases."
No, there is no rest stop southbound between exits 8 and 7a. There is the Molly Pitcher rest stop between exit 8a and 8 and the Richard Stockton service area between 7a and 7 but nothing in between 8 and 7a. for more see http://www.travelboards.com/turnpike/NJ/map.asp

To factorize the expression 7a^2 - 8ab, you need to find the greatest common factor of the two terms. In this case, the common factor is a. So, you can factor out an 'a' to get a(7a - 8b) as the factored form of the expression. This means that 7a^2 - 8ab can be simplified as a multiplied by the quantity (7a - 8b).
