v is -15... -15*2 = -30... -30+11= -19.
(-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
The Abelian (commutative) property of integers under addition.
its answer is probably -4.4 best of luckk!!!!!:)

4y + 7 = 19 ∴ 4y = 12 ∴ y = 3
x=2.75 This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
x=-6
In 2t+8 19
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
