It has to equal 3 because if you plug it in to the equation you get: (1+3)/2 = 2 4/2 = 2 2=2 check. To SOLVE for the equation you have to set the whole thing equal to X. (1+X)/2 = 2 1. Multiply both sides by 2. (2)(1+X)/2 = 2 (2) 2. subtract 1 from both sides. 1+X = 4 X-1 = 4 -1 3. This will give you your answer of 3. X = 3
9 and 8 4 and 3 3 and 2 2 and 1 if you subtract them.

1. Subtract 25 2. Then subtract 6 3. Then subtract 12 4. Then subtract 2 5. Then subtract 10 6. Then subtract 15 7. Then subtract 7 8. Then add 3 X 1/2 9. Then add 8
The answer is 0. For example, 1/3 - 1/3 = 0/3 which is equal to 0.

Yes, 1 1/2 + 1 1/2 = 2 2/2 or 3. The reason why are that real numbers and rational numbers are infinite and can add or subtract to make any number on the number line.
