4) Using the Gauss-Jordan method solve the following system of equations. You may use a calculator to solve but you must show your beginning and ending matrices. 2x + 4y =-6 Q. 2. -2 2x + 6y-4z =-4 a) State the row operations you would perform to the first column.

Explanation / Answer

Dear Student Thank you for using Chegg !! Given Set of equations 2x + 4y = -6 2x - 2z = 0 2x + 6y - 4z = -4 In matrix form 2 4 0 : -6 2 0 -2 : 0 2 6 -4 : -4 R2 - > R2 - R1 2 4 0 : -6 0 -4 -2 : 6 2 6 -4 : -4 R3 -> R3 - R1 2 4 0 : -6 0 -4 -2 : 6 0 2 -4 : 2 R3 -> R3 + 0.5X R2 2 4 0 : -6 0 -4 -2 : 6 0 0 -5 : 5 z = -1 -4y -2z = 6 -4y + 2 = 6 y = -1 2x + 4y = -6 2x - 4 = -6 x = -1 x,y,z = (-1,-1,-1) Solution
