Question 74728
{{{-1(2x+3y)=-1(1)}}}Multiply the 1st equation by -1
+{{{5x+3y=16}}}
---------------
{{{3x=15}}}
{{{x=5}}}
Plug this in to find y
{{{5(5)+3y=16}}}
{{{25+3y=16}}}
{{{3y=-9}}}
{{{y=-3}}}
So the solution is (5,-3). If you graphed the 2 equations, they would intersect at  (5,-3)
<p>
Check:
{{{2(5)+3(-3)=1}}}Plug in (5,-3)
{{{5(5)+3(-3)=16}}}
{{{10-9=1}}}
{{{25-9=16}}}
{{{1=1}}}works
{{{16=16}}}works
