tentukan bentuk bentuk oprasi aljabar berikut
a. A+b+C
b.2a-3b+4c
tolong banntuu bsk di kumpulll
Di berikan A=3x +1, b= -2x+3, dan c=4x-3
a+b+c = •••••?
= (3x+1) + (-2x+3) + (4x-3)
= 3x -2x +4x +1+3-3
= 5x +1 ✔
2a-3b+4c =••••?
= 2(3x+1) -3(-2x+3) +4(4x-3)
= 6x+2 + 6x -9 + 16x-12
= 6x+6x+16x +2-9-12
= 28x -19 ✔
a. A + B + C = (3x +1) + ( -2x+3) + ( 4x-3)
= (3x -2x+4x) + (1+3-3)
= 5x + 1
b. 2a-3b+4c = 2(3x+1) – 3(-2x+3) +4 (4x-3)
= (6x+2) + (6x-9) + (16x – 12)
= (6x + 6x +16x) + (2-9-12)
= 28x – 19
