Answer:
<em>Let the dryer cost x.</em>
<em>Then, the washer costs (x+87)</em>
<em> </em>
<em>Together, they cost (x) + (x+87) = 787</em>
<em> 2x+87 = 787</em>
<em> 2x = 700 [subtract 97 from both sides]</em>
<em> x = 350 [divide both sides by 2]</em>
<em> </em>
<em>The dryer cost $350.</em>
<em> </em>
<em>Check: The washer cost $437. Together, they cost $787 [good to check, right?]</em>
