(-11) + (+19) = -11 + 19 = 8
-8 + 19 = 11
The Abelian (commutative) property of integers under addition.
7.5
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
r + 11 = 19 r + 11 - 11 = 19 - 11 r = 8
A is 14
(-11) + (+19) = -11 + 19 = 8
-8 + 19 = 11
It is asking you to prove that you are a human, not a macro or bot trying to spam them with messages. Just do that math, and enter the number. In this case, the answer is 19.

its answer is probably -4.4 best of luckk!!!!!:)
7.5
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
x=-6
In 2t+8 19
