Hasil dari a)-8×+y-(4×-8y)= b)-2×-y+(3×-3y)= c)7×-2y-(×-7y)=

a. -8x + y - (4x - 8y)
= -8x + y - 4x + 8y
= -8x - 4x + y + 8y
= -12x + 9y

b. -2x - y + (3x - 3y)
= -2x + 3x - y - 3y
= x - 4y

c. 7x - 2y - (x - 7y)
= 7x - x - 2y + 7y
= 6x + 5y

a. -8x+y-(4x-8y)
= -8x +y -4x +8y
= -8x -4x +y +8y
= -12x +9y

b. -2x-y+(3x-3y)
= -2x-y+3x-3y
= x -4y

c. 7x-2y-(x-7y)
= 7x-2y-x+7y
= 6x +5y


semoga membantu .... ...
