a. 2(x+y)+3(x+y)
b. 5(x+y)+2(5x-y)
c. 5(x+y)+3(2x-y)
d. 3(2c+d)-2(4p-3)
e. 4(2p+2q)-3(2p-q)

A. 2(x + y) + 3(x + y)
    2(x) + 2(y) + 3(x) + 3(y)
    2x + 2y + 3x + 3y
    2x + 3x + 2y + 3y
    5x + 5y

b. 5(x + y) + 2(5x - y)
    5(x) + 5(y) + 2(5x) - 2(y)
    5x + 5y + 10x - 2y
    5x + 10x + 5y - 2y
    15x + 3y

c. 5(x + y) + 3(2x - y)
    5(x) + 5(y) + 3(2x) - 3(y)
    5x + 5y + 6x - 3y
    5x + 6x + 5y - 3y
    11x  + 2y

d. 3(2c + d) - 4(4p - 3)
    3(2c) + 3(d) - 4(4p) + 4(3)
    6c + 3d - 16p + 12

e. 4(2p + 2q) - 3(2p - q)
    4(2p) + 4(2q) - 3(2p) + 3(q)
    8p + 8q - 6p + 3q
    8p - 6p + 8q + 3q
    2p + 11q
