Sederhanakan bentuk aljabar berikut a. 5x - 6y + 8z + 7x - 9z - 2y + 9z -10 b. ( 2y + 15z ) - ( 4y - 8 ) c. ( 3x - 17y + 35 ) + ( 4x - 23y - 9z)

a. 12x-8y+8z-10
b. 15z-2y+8
c . 7x-40y-9z+35

a. 5x - 6y + 8z + 7x - 9z - 2y + 9z -10
5x+7x-6y-2y+8z-9z+9z-10 = 12x-8y+8z-10 = 2(6x-4y+4z-5)

b. ( 2y + 15z ) - ( 4y - 8 )
2y-4y+15z+8 = -2y+15z+8

c. ( 3x - 17y + 35 ) + ( 4x - 23y - 9z)
3x+4x-17y-23y-9z+35 = 7x-40y-9z+35

semoga membantu yaa:)
