Sederhanakanlah.
(1) 4a × (-2)
Jawaban
= 4 x (-2) x a
= -8a
(2) (-6) × (-5x)
Jawaban
= 30x
(3) 2(3x – 7)
Jawaban
= 6x – 14
(4) (x – 8) × (-3)
Jawaban
= -3x + 24
(5) (2x – 1)/3 x 6
Jawaban
= (2x – 1) x 2
= 4x – 2
(6) (-18a) : 6
Jawaban
= (-18/6) . a
= -3a
(7) 4x : 10
Jawaban
Sama-sama dibagi 2
= 2x/5
(8) (20a – 12) : 4
Jawaban
= (20/4) a – 12/4
= 5a – 3
