Answer 2

Answer:

The value for x, y, and z is {86,-9, -68}

Step-by-step explanation:

Given Equation

⇒ x + y + z = 9 ------------Eq.1

⇒ 2x - 3y + 4z = 13 -----------Eq.2

⇒ 3x - 4y + 5z = 40 ----------Eq.3

Solving Eq.1 and Eq.2 we get,

⇒ 2x + 7y = 23 ----------------Eq.4

Solving Eq.1 and Eq.3 we get,

⇒ 2x + 9y = 5 -----------------Eq.5

Solving Eq.5 and Eq.4 we get,

⇒ y = -9

⇒ x = 86

Putting x and y value in the Eq.1 we get,

⇒ z = -68
