4x + y =3<br> x + y - z = 9<br> 2x + 2y + z = 0

uranmaximum [27]

Answer:

$[0, 3, -6]$

Step-by-step explanation:

{4x + y = 3

{x + y - z = 9 ←

{2x + 2y + z = 0 ←

{4x + y = 3

{3x + 3y = 9 >> Combined equation

−¾[4x + y = 3]

{−3x - ¾y = −2¼ >> New Equation

{3x + 3y = 9

_________

2¼y = 6¾

___ ___

2¼ 2¼

$y = 3$ [Plug this back into all three equations to get the z-value of −6, and the x-value of 0]; $0 = x$ ; $-6 = z$
