How does 1 plus x divided by 2 equal 2?

Answer 1

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
