What is the solution to the system of equations? {x+3y-z=2 4x+2y+5z=1 3x+z=12 answer is (5,-2,-3)

it is definatly the 3rd one. very much looks like it, for a good chance, the third one would be best for you.

8(4)^8=72^feet to say that the total can conclude to 8(4) which as you know would mean 8 x 4. that equals 32w. 32^ could make a 72 answer as well. but your coefficent will remain w so your answer is 72w.
