Question

Solve x +2y+3z=1
2x+3y+8z=2
x+y+z=3. using Gauss elimination method​

Answer 1

:Answer

Simplifying

x + 2y + -3z = 1

Solving

x + 2y + -3z = 1

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2y' to each side of the equation.

x + 2y + -2y + -3z = 1 + -2y

Combine like terms: 2y + -2y = 0

x + 0 + -3z = 1 + -2y

x + -3z = 1 + -2y

Add '3z' to each side of the equation.

x + -3z + 3z = 1 + -2y + 3z

Combine like terms: -3z + 3z = 0

x + 0 = 1 + -2y + 3z

x = 1 + -2y + 3z

Simplifying

x = 1 + -2y + 3z
