You can put this solution on YOUR website! 2x - 3y - z = 0 3x + 2y + 2z = 2 x + 5y + 3z = 2 I will assume you have had matrices. If not, post again and I will show you how to solve it without matrices: The …

x - 2y + 3z = 11 2x - z = 3 3y + z = -8 The 2nd equation is the simplest and it already has y eliminated in it. so let's eliminate y also from the 1st and 3rd, so we'll have two equations with y eliminated in …

Question 53677: This is a question involving 3 variables, solve by elimination: 2x - 5y + 3z = -1 x + 4y - 2z = 9 x - 2y - 4z = -5 Answer by funmath (2933) (Show Source):

You can put this solution on YOUR website! the average of 2x + y + 3z is equal to (2x + 3y + z) / 6 there are 6 elements in all. 2 * x 1 * y 3 * z so, if you break them up, you get x + x + y + z + z + z. that's 6 …
