Question

Solve the system using 3x3

3x-2y+z=2

5x+y-2z=1

4x-3y+3z=7

Answer #1

Solve the sytem using elimination. Do not use augmentive
matrix.
(a) 3x - 2y + z = 2
(b) 5x + y - 2z = 1
(c) 4x - 3y + 3z = 7

Solve each system of equations
x-2y+3z=7
2x+y+z=4
-3x+2y-2z=-10

Use
Gaussian Elimination to solve and show all steps:
1. (x+4y=6)
(1/2x+1/3y=1/2)
2. (x-2y+3z=7)
(-3x+y+2z=-5)
(2x+2y+z=3)

#7 Solve for x, y and z
6x+3y+z=-27
x-3y+2z+10
17x-2y+3z=-65

for 7-9 you will solve the following system of equation :
2x+3u+z=17 x-3y+2z=-8 5x-2y+3z=5 7) what is the solution for x? a)2
b)1 c)infinitely many solution d)no solution 8)what is the solution
for y? a)4 b)2 c)inifinitely many solutions d)no solution 9) what
is the solution for z? a)9 b)1 c)inifinitely many solutions d)no
solution

Solve the system of equations using an inverse matrix
-4x-2y+z= 6
-x-y-2z= -3
2x+3y-z= -4
Choose one:
a. (-1, 0, -2)
b. (1, 0, -2)
c. (1, 0, 2)
d. (-1, 0, 2)

Solve the following system of equations.
{−x+4y−z=-4
3x−y+2z=6
2x−3y+3z=−2
Give your answer as an ordered triple
(x,y,z).

1. Solve by via Gauss-Jordan elimination:
a) 2y + 3z = 8
2x + 3y + z =
5
x − y − 2z =
−5
b) x + 3y + 2z = 5
x −
y + 3z = 3
3x + y + 8z = 10
c) 3x1 + x2 + x3 + 6x4 = 14
x1 − 2x2 +
5x3 − 5x4 = −7
4x1 + x2 + 2x3 + 7x4 =
17

Solve this system of equations.
4x + 3y + z = -4
x - 3y + 2z = -25
11x - 2y +3z = -63
Write the solution as an ordered triple.
PLEASE MAKE SURE THIS IS CORRECT. I KEEP PAYING FOR THE WRONG
ANSWERS.

1. Solve the following system of equations by the elimination
method:
2x+y-z=7
x+2y+z=8
x-2y+3z=2
2. Solve the following system of equations by using row
operations on a matrix:
2x+y-z=7
x+2y+z=8
x-2y+3z=2
