1. Explain why vectors QR and RQ are not equivalent. 2. Explain when the elimination method for solving a system of equations is preferable to the substitution method. It is extremely important for you to show your work. This helps me immensely, as I am much better working backwards when it comes to math problems and soluti
Use matrices to solve the system of equations (if possible). Use Gaussian elimination with back substitution or Gauss-Jordan elimination. Explain steps and show work. 2x + 2y - z= 2 x - 3y + z= -28 -x + y = 14
How do you explain why vectors QR and RQ are not equivalent? Explain when the elimination method for solving a system of equations is preferable to the substitution method. I need step by step help in solving these problems
See the attached file. 1. Solve to the homogenous system of linear equations. {2x - 2y + z = 0 both equations are in the same { {-2x + y + z = 0 I got the following: x = ¾c, y = -c, z = 1/2c 2. Find the real solutions to the system of equations using the addition method. x^2 + 8y^2 = 5 x^2 - 4y

Please explain clearly the steps to solving by substitution: z = 4x - 3y + 15 2x = y - 8 z = 6y (No replies using power point, please.)
The idea of this problem is to investigate solutions to x2≡1(mod pq) where p and q are distinct odd primes. (a) Show that if p is an odd prime, then there are exactly two solutions modulo p to x2≡1(mod p). (b) Find all pairs (a,b) Є Zp x Zq such that a2≡1(mod p) and b2≡1(mod q). (c) Let p=17 an

I am needing this to be illustrated if you wi
I am asking for assistance with the below questions: 1. Explain why vectors QR and RQ are not equivalent. 2. Explain in your own words when the elimination method for solving a system of equations is preferable to the substitution method. I have attempted to answer the questions but am wishing to see if done correctly
