x + 3 y + 4 z = 15

$x + 3 y + 4 z = 15$ ,

2 x - y + z = 2

$2 x - y + z = 2$

Bước 1

x + 3 y + 4 z = 15, 2 x - y + z = 2

$x + 3 y + 4 z = 15, 2 x - y + z = 2$

[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
