Question 1106693
<br>
Simply solve the pair of equations by any method you like.<br>
For pairs of linear equations like these, my preference is to use the elimination method.<br>
{{{2x+7p = 56}}}
{{{3x-11p = -45}}}<br>
Multiply the first equation by 3 and the second by -2 and add; that eliminates variable x so you can solve for p.  Then substitute the p value into either original equation to solve for x.
