Sederhanakan bentuk aljabar berikut ! 1. (2x + 8) + (4x -5 -5y) 2. (3p+q) + (-2p -5q + 7) 3. (5a-6+ab) - (a+2ab-1) jawabyaa plss!!

Aljabar
---------

Cara Mengerjakan :
Kumpulkanlah variabel yang sama

1]. (2x + 8) + (4x - 5 - 5y)
= 2x + 8 + 4x - 5 - 5y
= 2x + 4x - 5y + 8 - 5
= 6x - 5y + 3

2]. (3p + q) + (-2p - 5q + 7)
= 3p + q - 2p - 5q + 7
= 3p - 2p + q - 5q + 7
= p - 4q + 7

3]. (5a - 6 + ab) - (a + 2ab - 1)
= 5a - 6 + ab - a + 2ab + 1
= 5a - a + ab + 2ab - 6 + 1
= 4a + 3ab - 5

1. (2x + 8) + (4x -5 -5y) = 2x + 8 + 4x - 5 - 5y = (2 + 4)x - 5y + (8 - 5) = 6x - 5y + 3

2. (3p+q) + (-2p -5q + 7) = 3p + q - 2p - 5q +7 = (3 - 2)p + (-5 + 1)q + 7 = p - 4q + 7

3. (5a-6+ab) - (a+2ab-1) = 5a - 6 + ab - a + 2ab + 1 = (1 + 2)ab + (5 - 1)a + (-6 +1) = 3ab + 4a -5
