ok so you have to use the process of elimination

anonymous · Answer

You can do this by solving for the two equations given to you. I assume you already know now to do that so, I will go ahead and say it is $x = 3,$ $y = -5$.

1) $11x = 19$ $\implies$ $x = 1.72727272$
2) $11y = -55$ $\implies$ $y = -5$
3) $11x = 33$ $\implies$ $x = 3$

Both answer choice 2 and 3 are equal to the solution, however 1 is not, so 1 is your answer. If I assumed wrong on whether or not you know how to solve systems of linear equations let me know, and I will teach you so just ask ^-^
