Answer:

x=2

y=1

Step-by-step explanation:

-6x+12=0

take 12 to the other side &it becomes negated then equate

-6x=-12

the negatives cancel out each other and therefore the answer is positive

x=2

4y+5=9

take 5 over to the other side &it becomes negated

4y=9-5

4y=4

y=1

bagirrra123 [75]

To find the amount of money you pay for tax, you have to multiply the price of the product by the percentage of the tax, then divide it by 100. in this case, 76x5.6=425.6/100=4.256 which is $4.26 (to the nearest cent)
