(1) x+2y-z=5

Jawaban:

$sf large1. : x = - 2y + z + 5$

$sf large2. : x = frac{1}{3} y - frac{1}{3} z + frac{4}{3}$

Penjelasan dengan langkah-langkah:

$sf large 1. : x + 2y - z = 5$

$sf large = x = 5 - (2y) + z$

$sf large = x = - 2y + z + 5$

==============================

$sf large 2. : 3x - y + z = 3$

$sf large = 3x = 4 + y - z$

$sf large = 3x = y - z + 4$

$sf large = x = (y - z + 4) div 3$

$sf large = x = (y - z + 4) times frac{1}{3} \$

$sf large = x = frac{1}{3} y - frac{1}{3} z + 4 times frac{1}{3} \$

$sf large = x = frac{1}{3} y - frac{1}{3} z + frac{4}{3}$

Maaf kak yg nomer 3 gk bisa yaa
