Let e=erasers and p=pencils. So we know the total amount of erasers plus pencils sold is equal to 220. Therefore,

We also know the cost of erasers and pencils totaled to $695 in earnings and so:

and so those are your two equations.
{5x-7y=-2
<u>{-5x-10y=-15 </u>(+)
<em>5x-5x-7y-10y=-17</em>
<em> </em>-17y=-17 /:(-17)
y=1
<em /><em>5x-7 *1=-2</em>
<em />5x-7=-2 /+7
5x=5 /:5
x=1
<u>Solution:</u> (1; 1)
