A = 3x - 5 + 5 (2x - 2)

A = 3x - 5 + 10x - 10

A = 3x + 10x - 5 - 10

A = 13x - 15

B = 4y - 6 (3 - 2y) + 4 (y - 1)

B = 4y - 18 + 12y + 4y - 4

B = 4y + 4y + 12y - 18 - 4

B = 20y - 22

C = 5t² + 3 (2t - 3) - 2t (t - 5)

C = 5t² + 6t - 9 - 2t² + 10t

C = 5t² - 2t² + 6t + 10t - 9

C = 3t² + 16t - 9

D = 3 (2x - 6) - (3 - 5x)

D = 6x - 18 - 3 + 5x

D = 6x + 5x - 18 - 3

D = 11x - 21

E = (5 - 2y) - (- 3y + 7)

E = 5 - 2y + 3y - 7

E = y - 2.
