Obviously you meant that p was the price before sales tax and $6.35 was the price *after* sales tax. If so, your equation is correct:
p + 0.06p = 6.35
Distribute out the common p:
(1 + 0.06)p = 6.35
(1.06)p = 6.35
Divide both sides by 1.06:
p = 6.35/1.06
Just plug this in your calculator, or multiply numerator and denominator by 100 and use long division:
p = 635/106
p = 5.99
As a double check:
$5.99 * 0.06 = 0.36, so the total price would be $6.35.
The item cost $5.99 before 6% tax was added.

You said $6.35 is the price not including sales tax, but your equation says $6.35 is the price including tax. So which one is it?

Using your equation, I would combine terms on the left side so that 1p+0.06p=6.35 becomes 1.06p=6.35 then divide bothsides by 1.06 to get p=5.99 (rounded off)

6.35 * .06 = .381
.381 + 6.35 = 6.731
round up and you get 6.73
this is if what you said that the 6.35 is without sales tax
i do think you sould reask the question and do it clearly

p + 0.06p = 6.35
add the p's together to get
1.06p = 6.35
divide both sides by 1.06
p = 5.99
