x=2.75
This follows from the equation (4x - 3) + 11 = 19 and 4x = 11
(-11) + (+19) = -11 + 19 = 8
-8 + 19 = 11

v is -15... -15*2 = -30... -30+11= -19.
(-11) + (+19) = -11 + 19 = 8
-8 + 19 = 11
r + 11 = 19 r + 11 - 11 = 19 - 11 r = 8

x=-6
In 2t+8 19
v is -15... -15*2 = -30... -30+11= -19.
-19 plus 144 equals 125.
q=-6
x +8=19 subtract 8 from both sides x=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.
