Tolong aku mengerjakan yang tabel, TUGAS DIKUMPULKAN SEKARANG

4) A + B
= (3x - 2) + (2x - 4)
= 3x + 2x - 2 - 4
= 5x - 6
B + A
= (2x - 4) + (3x - 2)
= 2x + 3x - 4 - 2
= 5x - 6

6) A - B
= (2x - 1) - (1 - x)
= 2x + x - 1 - 1
= 3x - 2
B - A
= (1 - x) - (2x - 1)
= 1 + 1 - x - 2x
= 2 - 2x
= - 2x + 2

7) A + B
= 3x + (2x + 1)
= 5x + 1
B + A
= (2x + 1) + 3x
= 5x + 1

8) A + B
= 5 + (2x - 4)
= 2x + 5 - 4
= 2x + 1
B - A
= (2x - 4) - 5
= 2x - 9

semoga membantu yaa..
