Answer 1

a) 5x + 4y
b) 5(x + 2y)
c) -7× -15y
d) 7/6 x + 9/4 y

Answer 2

a) - 4x + 6y + 10x - 2y - x = 6y - 2y - 5x + 10x = 5x + 4y

b) x + 7x + 10y - 3x = 8x - 3x + 10y = 5x + 10y

c) 2x - 8y - 6y - y - 9x = 2x - 9x - 15y = - 7x - 15y

d) 3/2x + 1/4y - 1/3x + 2y = 3/2x - 1/3x + 1/4y + 2y = x(3/2 - 1/3) + y(1/4 + 2) = x(9 - 2/6) + y(1+8/4) = 7/6x + 9/4y
