Question

1.5(x-2y)-3(2x-y)=
2.-3(x-4y)+4(5x-3y)=
harus pakai cara!!!!

Answer 1

5(x - 2y) - 3(2x - y)
5(x) + 5(-2y) - 3(2x) - 3(-y)
5x - 10y - 6x + 3y
5x - 6x - 10y + 3y
-x - 7y

-3(x - 4y) + 4(5x - 3y)
-3(x) - 3(-4y) + 4(5x) + 4(-3y)
-3x + 12y + 20x - 12y
-3x + 20x + 12y - 12y
17x

Answer 2

1. 5x - 10y - 6x + 3y
= 5x - 6x - 10y + 3y
= -1x - 7y

2. -3x + 12y + 20x - 12y
= -3x + 20x + 12y - 12y
= 17x
