The answer is D because they take a tile out which makes it 7 tiles in the bag but then they put it back which makes the bag have 8 tiles in it again.
1 2/3 + 1 5/6
We’ll start by converting the 2/3 to 6ths so we have a common denominator.
Look at the denominator first. 3 x 2 is 6, so we need to multiply the numerator by 2 as well. 2/3 = 4/6.
So we have 1 4/6 + 1 5/6 = 2 9/6
But you know they’ll want you to reduce that so it’s 3 3/6...or 3 1/2.
Let me know where you have questions.
X=2
-4 on both sides
4=2x
divide by 2 on both sides
X=2
