2x + y = x - y - 3 = 6
Add 3 to everything
2x + y + 3 = x - y - 3 + 3 = 6 + 3
2x + y + 3 = x - y = 9
2x + y + 3 = 9
2x + y = 6 = x - y
Add y to everything
2x + 2y = 6 + y = x
Since x = 6 + y substitute every x with 6 + y
2(6 + y) + 2y = x
12 + 4y = x
This is as simplified as I can get and then just place 12 + 4y into every x in the original problem then solve
Answer:

Step-by-step explanation:
We have been given that Ross chose a card at random from a deck of 52 cards. Ross replaced the card and then chose a second card.
Let us find probability of getting a club.

Now let us find probability of getting the ace of spades.

Now let us multiply these to find probability of getting a club and ace of spades.
Therefore, probability of getting a club and then the ace of spades
.
Answer:

Step-by-step explanation:
1.5(2^x)(2^1)
1.5x2^x x2
3x2^x
The answer is D because 42 / 6 = 7 and the power ( ^X) can cancel out each other
