|3x|=9
3x=9 -3x=9
X=9/3 x=9/-3
x=3 x=-3
Whenever you have an absolute value sign you have to find both the positive and the negative because they didnt signs into the equation but sometimes a question will ask for strictly the positive value or the negative value but if its not stated, find both.
The answer would be x equals all real numbers because you can't take the root of a negative number.

Answer:
See explanation below.
Step-by-step explanation:
First, obtain the percentage of sales tax for a sale. Say it is 5%.
Then, obtain the sale prices, for two items say they are: $25.00 and $15.00.
Add the amounts together to obtain the subtotal:
$25.00 + $15.00 = $40.00, is the subtotal.
Multiply the amount by the percentage:
$40.00 * 5% =
40 * .05 = $2.00, is the sales tax
Add the tax to the subtotal to obtain the total amount to pay:
$40.00 + $2.00 = $42.00, is the total amount to pay.
Hope this helps!! Have an Awesome Day!! :-)
