Question 196290
Yes you can, however it is important to simplify the equation.
{{{7x+2y=-5}}}
{{{2y=-5-7x}}} Just subtracted both sides by 7x.
{{{y=(-5-7x)/2}}} Just divided both sides by 2.

Now if you jumble around the equation a little, it begins to look a lot like {{{y=mx+b}}}

{{{Y=-3.5X-2.5}}}
