Question 71886
To solve this, plug in the solution (-3,4) into the system
{{{5(-3) + 7(4) = b}}}Plug in (-3,4) for the first equation
{{{-15+28=b}}}
{{{b=13}}}
{{{m(-3) + (4) = 22}}}Solve for m
{{{-3m=18}}}
{{{m=-6}}}
So the following system will give you a solution of (-3,4)
<pre>
            5x + 7y = 13
           -6x + y = 22
                           </pre>
To verify it, either plug in (-3,4) into the system or graph it to find the intersection of (-3,4) (you have to solve for y first).
