Jika A = 1 per 2 dan b = - 1 carilah nilai dari (3 a + b) - (A + 4 b)
![]()
Jawaban:
[tex]3( \frac{1}{2} ) + ( - 1) - ( \frac{1}{2} + 4( - 1)) \\ \\ = \frac{3}{2} - 1 - \frac{1}{2} + 4 \\ = 4 \\ [/tex]
Penjelasan dengan langkah-langkah:
semoga membantu
(3.1/2 + (-1)) - (1/2 + 4.(-1))
= (3/2 - 1) - (1/2 - 4)
= (3/2 - 2/2) - (1/2 - 8/2)
= 1/2 - 7/2
= -6/2
= -3
