2( a + 5 ) - 8(a + 1 ) =
-(a - 8 ) - 5 (-2a +4 ) = ![]()
-(a - 8 ) - 5 (-2a +4 ) =
Penjelasan dengan langkah-langkah:
Bagian 1)
= 2(a + 5) - 8(a + 1)
= 2a + 10 - 8a - 8
= 2a - 8a + 10 - 8
= (2 - 8)a + 10 - 8
= -6a + 2
Bagian 2)
= -(a - 8) - 5(-2a + 4)
= -a + 8 + 10a - 20
= -a + 10a + 8 - 20
= 9a - 12
