Step-by-step explanation:
10 - 5y + y = - 6
10 - 4y = - 6
-4y = - 6 - 10
-4y = - 16
y = - 16 / - 4
y = 4
Answer:
Sales Tax In Amount =$99
Total amount of purchase = $1899
Step-by-step explanation:
First, let's find sales tax price in amount(dollars)
(Total Amount)*(percentage of tax)/100=Tax in amount
(1800)*(5.5%)/100 = $99
Therefore, the sales tax in amount would equal to $99, which is the same as 5.5%.
Now, let's find the total price of the purchase.
$1800+$99= $1899
So, the total cost of the purchase would equal to $1899.
5x + 8y = 4.....when x = 4
5(4) + 8y = 4
20 + 8y = 4
8y = 4 - 20
8y = - 16
y = -16/8
y = -2 <==
42.60
Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaazaaaaaaaaaaaa
if you multiply each x by -5 you will get each y
