The dryer costs x.
The washer costs $93 more than the dryer, so it costs x+93.
The washer and the dryer cost $793 altogether.

\(x+x+93=793 \\ 2x=793-93 \\ 2x=700 \\ x=\frac{700}{2} \\ x=350\)

The cost of the dryer is $350.

let x= dryer
x+93= washer

x+ x+93=793
combine like terms
2x+93= 793
subtract 93 from both sides
2x=700
divide by 2
x= 350
the dryer cost $350

hope this helps
