A = 5 (x + 3)
A = 5*x + 5*3
A = 5x + 15
B = 2 (x - 8)
B = 2*x - 2*8
B = 2x - 16
C = 4 (3x + 2)
C = 4*3x + 4*2
C = 12x + 8
D = - 7 (3 - 4x)
D = - 7*3 - 7*(- 4x)
D = - 21 + 28x
E = 5 (x - 1) + 2 (x + 4)
E = 5*x - 5*1 + 2*x + 2*4
E = 5x - 5 + 2x + 8
E = 7x + 3
F = 8 (x + 2) - 6 (x - 9)
F = 8*x + 8*2 - 6*x - 6*(- 9)
F = 8x + 16 - 6x + 54
F = 2x + 70
G = 3 (2x - 5) - 4 (2 + 5x)
G = 3*2x - 3*5 - 4*2 - 4*5x
G = 6x - 15 - 8 - 20x
G = - 14x - 23
H = - 5 (x - 2) + 2 (6x + 7)
H = - 5*x - 5*(- 2) + 2*6x + 2*7
H = - 5x + 10 + 12x + 14
H = 7x + 24
I = - 4 (5 - 2x) - 9 (3x - 1)
I = - 4*5 - 4 *(- 2x) - 9*3x - 9*(- 1)
I = - 20 + 8x - 27x + 9
I = - 19x - 11
