Add the two functions together to get
7y=-3
y=-3/7
Then plug in y to either function to solve for x, I’ll just use the left one
15(-3/7)-9x=-9
-45/7-9x=-9
-9x=-18/7
x=18/7/9
x=2/7

Logic:
(1) A bag contains red and green beans.
(2) The probability of choosing a red bean at random stands at 2/5.
*This means that there are 2 red beans and 3 green beans in this bag.
Answer:
The probability of choosing a green bean at random would have to stand at 3/5 because of the logic above. There are 5 beans in the bag, 2 of which are red and 3 of which are green.
An item that costs $205000, when discounted 15 percent, will cost $174250. The easiest way of calculating discount is, in this case, to multiply the normal price $205000 by 15 then divide it by one hundred. So, the discount is equal to $30750. To calculate the sales price, simply deduct the discount of $30750 from the original price $205000 then get $174250 as the sales price. which mean is C
