a= -4

m = 8
(2, 3)
x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
2+14=16
I x=5 and y=2, then (5x5)=25 plus (9x2)=18. 25+18=43
few errors in your title: 2 plus 4 = 6 6 plus 9 = 15 10 plus 25 = 35 18 + 81 = 99
16

No. -18 / 3 = -6
16/8 equals 2

x^2 + 3x + 7 = 6x + 18 x^2 - 3x - 11 = 0
-4b+2 = 18 -4b = 18-2 -4b = 16 b = -4
