Question

Solve the system of linear equations:

x + y - 3z = 9
y + z - 3x = 5
z + x - 3y = 1
Find x y and z

Answer 1

Answer: x= 5/2, y= 11, z= 3/2

Explanation:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point form:

(5/2, 11, 3/2)
