8b = e - 12n, possibly.
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
That's an equation in which b = -1
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
7b + 16 = 5b + 247b - 5b = 24 - 162b = 8b = 4
b^2 + 8b + 7 factors to (b + 7)(b + 1)
8b
13b !
8b^2 -9b +1 8b^2 -8b -b +1 8b(b-1) - 1(b-1) (8b-1)(b-1)
Amazing! Exactly the same question was posted here on WikiAnswerslast September 23. What an incredible coincidence!8b + 11 - 3b = 2b + 2That 8b on the left side can be combined with the -3b to make 5b .5b + 11 = 2b + 2Subtract 2b from each side:3b + 11 = 2Subtract 11 from each side:3b = -9Divide each side by 3:b = -3(That's the same answer they got last September.)
22b + 3
5b2 = 8b therefore 5b =8 therefore b = 1.6
