I don't understand this one plz help before sunday.(Thank may God bless you and back the blue)
Makovka662 [10]

Answer:

2/3(3/4x-3/2) = 1/2x-1

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

Step-by-step explanation:

1) Distribute 2/3 to both 3/4x and -3/2

2/3(3/4x) = 6/12x which can be simplified as 1/2x

2/3(-3/2) = -6/6 which simplifies to -1

2/3(3/4x-3/2) = 1/2x-1

2) (2x+1) - (x+3/2) combine like terms

2x-x = x

1 - 3/2= 1- 1 1/2 ( change 3/2 into an improper fraction. 2 goes into 3 one time with one left over. Place the “leftover” back on top of the original denominator of 2)

1- 1 1/2 = -1/2, so

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