Question 111746

{{{4*q-3*p=22}}} Start with the given equation



Let's test the first solution (2,-4):



{{{4*(2)-3*(-4)=22}}} Plug in {{{q=2}}} and  {{{p=-4}}}



{{{20=22}}} Simplify. Since the two sides of the equation are <font size=4><b>not</b></font> equal, this means (2,-4) is <font size=4><b>not</b></font> a solution to {{{4*q-3*p=22}}}
