x = 0
here's an explanation
3x = 9x
subract 9x from both sides
3x - 9x = 6x 9x - 9x = 0
this gives you
6x = 0
divide 6x on both sides
6x/6 = x 0/6 = 0
x = 0

Given that <span>Marjorie received successive discounts of 25%, 40% and 20% off the original price, on Black Friday.
</span><span>If
Marjorie wanted to purchase the same items this week, the single
