Question 370091: Use the elimination method to solve the following system of equations. x + 3y z = 2 x 2y + 3z = 7 x + 2y 5z = 21 Found 2 solutions by Fombitz, CharlesG2:

Question 514509: Formulate but do not solve the problem. Cantwell Associates, a real estate developer, is planning to build a new apartment complex consisting of x one-bedroom units, y two-bedroom …

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 …
