Question 70168
Plug in pair into both equations to determine if true or false.
Let x=-5, y=2
{{{2(-5)+3(2)=-4}}}
{{{-10+6=-4}}}
{{{-4=-4}}}true
and test the other equation
{{{(-5)-4(2)=-10}}}
{{{-5-8=-10}}}
{{{-13=-10}}}false
Since one equation tested false the pair is not a solution of the system.
