10-Minute Brain Games: Logic and Reasoning

Matematika (x-8)-(2×-5)=
(4 a +9)- (a+3)=​

(x-8)-(2×-5)=
(4 a +9)- (a+3)=​

Penjelasan dengan langkah-langkah:

Bagian 1)

= (x - 8) - (2x - 5)

= x - 8 - 2x + 5

= x - 2x - 8 + 5

= (1 - 2)x - 8 + 5

= -1x - 3

= -x - 3

Bagian 2)

= (4a + 9) - (a + 3)

= 4a + 9 - a - 3

= 4a - a + 9 - 3

= (4 - 1)a + (9 - 3)

= 3a + 6
