penjumlahan dan pengurangan dari (2p +3q -4) 4(p -3q +2)= (6xy + 3yz +4z) + (3yz +4yx - 4Z) (2b -3x +5c)- (5a - 2c -3b) -3 (2c + 1) - (p + 5) dijawab cepet ya

1. ( 2p +3q -4) + 4 (p -3q +2)
= 2p +3q -4 + 4p - 12q + 8
= 2p +4p +3q -12q - 4 +8
= 6p - 9q +4

2, 6xy +3yz +4z + 3yz + 4xy - 4z
= 6xy +4xy +3yz +3yz +4z -4z
= 10xy +6yz

3. 2b -3x +5c - 5a + 2c + 3b
= -5a +2b +3b +5c +2c -3x
= -5a +5b +7c -3x

4. -3 (2c +1) - (p +5)
= -6c -3 - p -5
= -6c -p -3-5
= -6c -p -8
