There are two black queens in a standard deck, so the probability is 2/52 or 1/26.
If instead you know you pulled a black card from the deck and you’re wondering what the probably is that it’s a queen, then it’s 2/26, since there are still 2 black queens, but only 26 black cards.
First, simplify. Combine like terms
10x - 3x = 7x
7x + 1 = x + 4
Isolate the x. Subtract x from both sides, and 1 from both sides
7x (-x) + 1 (-1) = x (-x) + 4 (-1)
7x - x = 4 - 1
Simplify
6x = 3
Isolate the x. Divide 6 from both sides
6x/6 = 3/6
x = 1/2
1/2, or 0.5 is your answer for x.

1.5x+6-3=4.5(x-2)
1.5x+6-3=4.5x-9
1.5x+3=4.5x-9
1.5x-4.5x+3=-9
1.5x-4.5x=-9-3
-3x=-9-3
-3=-12
