x = 6
If: 12 = x+6 Then: x = 6
(x+5)(x+6) equals x^2 +11x+30
X=5, x+6, 5+6=11
It is 4x2 + 426x + 630.
x > -5
No it equals 6 because x and y equal 1 in themselves
3x + 18
11. cuz 5+6=11
It is a straight line equation in the form of x+y = 6
i assume you mean what does x equal in this case. and the solution is x=6. x+x=10+2 2x=12 x=6
X equals 6
