Ini jawaban sama caranya gmana?? jelas gak??

Answer 1

1. a. (5x +3y) + (2x-3y)
= (5x+2x) + (3y-3y) = 7x
b. (4a+b-3c-d) + (2a+3b-2c+3d)
=6a+4b-c+2d
c (3a + 5b+3c+6d) + (6a-7b-7c-2d)
= (3a+6a) + (5b -7b) + (3c-7c) + (6d -2d)
= 9a -2b -4c + 4d
d. (5p+2r-3a+6c)+(7p-2r-3a-6c)
= (5p+7p) + (2r-2r)-(3a-3a) -6c-6c
= 12p
