Question 1118973
<br>
Option A, translated into algebra, says
{{{9(3)+5(-5) = 2}}}  and  {{{7(3)-4(-5) = 1}}}<br>
Since the first equation is true but the second is not, option A is not the right matrix equation.<br>
Check each of the other options to find the right one.<br>
Note that all the options have the same second matrix except for the signs, so it should be easy to find the correct one.
