It doesn't, 7+2=9
A^2 + b = 7 A + B^2 =11 -------------- A=2 and B=34(2^2) + 3 = 7 2 + 9(3^2) = 11
-2 - 9 + (-7) = -2 - 9 - 7 = -11 - 7 = = -18 the answer to this is (-18)
2+3 = 5 * 2 = 10. 7+2 = 9 * 7 = 63.6+5 = 11 * 6 = 66.x+y = z * x = n.9+7 = 16 * 9 = 144
11 + 7 + 9 = 27
22
Negative 11
It doesn't ! -7 plus -5 equals -12 ! -7 plus 5 equals -2
basically you asked what -28+21 which equals -7
-7 + 11 = +4
96
9s + 7 = -11 9s = -18 s = -18/9 s = -2
If I am correct, 9 plus 7 equals 112.
