Question 101338: Could you please take the time to help me solve this question: Solve the following system of three linear equations: 2x + y + z = 3, -x + 2y + 2z = 1 and x - y - 3z = -6. Noting that each equation represents a plane, interpret your results.
Thank you, very much for taking the time to help me, most appreciated
Answer by MathLover1(20850) (Show Source): You can put this solution on YOUR website!
first take these two equations:
(multiply both sides by in this one)
then we will have
now we will eliminate by adding them and it will be:
now divide both sides by ,and we will have:
then we have
which we can put in third equation
and we will have
from this equation
since we have and , we can use them to calculate :
let use the second equation
substitute and
now is easy to calculate and
