Solve the following system of equations x plus 2y -6 equals z 3y-2z equals 7 4 plus 3x equals 2y -5z?

x+2y-6=z

-z -z

x+2y-z-6=0

+6 +6

---------> x+2y-z=6

3y-2z=7

---------> 0x+3y-2z=7

4+3x=2y-5z

-3x -3x

---------> -3x+2y-5z=4

Put them into a matrix, for x,y,z and their answers. Solve for [A]-1[B], and the answer comes to:

x= 1.75, y= 1.5, and z= -1.25
