Isolate the variable by dividing each side by factors that don't contain the variable
The rule for reflecting a point over the y-axis is this:

Answer:
$350
Step-by-step explanation:
Let d = price of dryer
Then d - 61 is the price of the washer.
The sum of the prices is $639.
d + d - 61 = 639
2d - 61 = 639
2d = 700
d = 350
The price of the dryer is $350
2x+40=3x-85
2x-3x+40=3x-3x-85
-x+40=-85
-x+40-40=-85-40
-x=-125
Multiply by -1 to get positive x and for -125
(-1)(-x)=(-125)(-1)
x=125
Check answer by using substitution method
2(125)+40=3(125)-85
250+40=375-85
290=290
Answer is x=125
