In order to keep the equation right, both sides have to balance each other. When you only perform an operation ( I'm assuming you're talking about division or multiplication) on one side, it messes up the balance because now one side is larger than the other.
Since it's an ordinary deck, there are 52 cards in the deck. Assume the deck is fair.
Winning cards are spades and there 13 of those in the deck - the numbers 2 through 10 (9 if them), the three face cards (J, Q, K), and the A.
Winning cards are also aces are there four of them - one for each suit (Hearts, clubs, diamonds, spades)
However the Ace of spades is among both groups so we remove it from the last group to avoid double counting. (You could from the first, but the subtraction is a must)
So there are 13 + 4 - 1 = 16 winning cards out of the deck of 52.
Thus our probability is 16/52.
10.Let's solve for f.
gx=fx−4
Step 1: Flip the equation.
fx−4=gx
Step 2: Add 4 to both sides.
fx−4+4=gx+4
fx=gx+4
Step 3: Divide both sides by x.
fx/x=gx+4/x
The correct answer would be f= gx+4/x
11. Let's solve for f.
hx=12fx+2
Step 1: Flip the equation.
12fx+2=hx
Step 2: Add -2 to both sides.
12fx+2+−2=hx+−2
12fx=hx−2
Step 3: Divide both sides by 12x.
12fx/12x = hx-2/12x
The correct answer would be F= hx-2/12x
12. Let's solve for f.
kx=(−2f)(−x)
Step 1: Flip the equation.
2fx=kx
Step 2: Divide both sides by 2x
2fx/2x= kx/2x
The correct answer would be F= k/2

Answer:
10d - 3x
Step-by-step explanation:
Distribute the 4: 12d - 8x
Distribute the -1: -2d + 5x
Add like terms: 10d - 3x
