Question 3 options:

equivalent to 1/2x − 1

equivalent to x − 1/2

not equivalent to 1/2x − 1 or x − 1/2

Answer 1

Answer:

equivalent to x - 1/2

Step-by-step explanation:

(2x+1) - (x+3/2)

distribute -1(x+3/2) = -x-3/2

bring down 2x+1 and also -x-3/2   put it together 2x+1 -x -3/2

combine like terms: 2x +1 -x -3/2  

(2x-x = x)  (-3/2+1= -1/2)

Answer= equivalent to x - 1/2
