Question

What is the solution to the system of equations? -3x-y+z=6 -3x-y+3z=0 x-3z=3

Answer 1

Answer:X/3X=3

We move all terms to the left:

X/3X-(3)=0

Domain of the equation: 3X!=0

X!=0/3

X!=0

X∈R

We multiply all the terms by the denominator

X-3*3X=0

Wy multiply elements

X-9X=0

We add all the numbers together, and all the variables

-8X=0

X=0/-8

X=0
