Question

5x + 2y = 5
3x - y = 14
Which of the following equations is not a result of solving the system of equations by addition?
11x = 19
11y = -55
Or
11x = 33

Answer 1

try multiplying the bottom equation by 2 and then add it to the top equation.

Answer 2

Step easy here. Note the question is one of those sneaky kind that ask "is not" a result of solving by using the "elimination" method. It then list some options.
The first one is not the proper results. Because if you do as requested by @RBauer4 you would get the value value 11x=33, this is the results you would get, so it isn't a "is not"

This leaves the 11y = -55, it too is what you would get if you tried to eliminate the x and then solve for y, so it isn't an "is not" So the first one is the one that is a "is not" lol.
