A= 5-(2 – 3x) + (2x + 1)
A = 5 - 2 + 3x + 2x + 1
A = 5 - 2 + 1 + 3x + 2x
A = 4 + 5x
A = 5x + 4
B = 2-(3 - 5x) - (-x+1)
B = 2 - 3 + 5x + x - 1
B = 5x + x + 2 - 3 - 1
B = 6x - 2
C=-x- (2x + 3) - (1 - 2x)
C = -x - 2x - 3 - 1 + 2x
C = -x - 2x + 2x - 3 - 1
C = -x - 4
D= 2x - (3 + 4x) + (1 - x)
D = 2x - 3 - 4x + 1 - x
D = 2x - 4x - x - 3 + 1
D = -3x - 2
