The correct answer would be the third option. <span>The first equation can be multiplied by –12 and the second equation by 5 to eliminate x. Calculations are as follows:

</span>-12(5x + 13y = 232)
<span>5(12x + 7y = 218)
</span>
-60<span>x - 156y =-2784
</span>60<span>x + 35y =1090
</span>
<span>Adding the two equations, we obtain the value of y.
</span>-121y = -1694
y = 14
