y = 6 and z = -3
3y+2z
x = 3 and y = 0
No.
-3y + z = 12
See definition of polynomial and monomials. You will see.
3x 3y + 6z = 12
Solve this system of equations. 5x+3y+z=-29 x-3y+2z=23 14x-2y+3z=-18 Write the solution as an ordered triple.
3y+2z
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
x = 3 and y = 0
what do you want to be solved?
No.
-3y + z = 12
4x+3y = 12 3y = -4x+12 y = -4/3x+4
See definition of polynomial and monomials. You will see.
The ordered triple is (x, y, z) = (1, -1, -2)
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
