Question

Solve the system by elimination.
x+5y-4z=-10
2x-y+5z=-9
2x-10y-5z=0

Answer 1

Gauss Elimination/ the Gauss Jordan method

Answer 2

?

Answer 3

i am sorry but do you know matrices and determinants and how to put an equation in the form of a matrix etc..?

Answer 4

not really i have absolutely no clue how to solve this

Answer 5

oh then just go by eliminating one variable at a time....ex: from first eq eliminate x by taking x=-10+4z-5y and put it in the second equation..then eliminate y...put it in the third..you will get z...and from that x and y
