Question

Solve the system of equations. Explain how please!

3x-5y+4z= -19

4x-3y-3z= -34

x-y+4z = 13

Answer #1

Solve each system by elimination.
1) -x-5y-5z=2
4x-5y+4z=19
x+5y-z=-20
2) -4x-5y-z=18
-2x-5y-2z=12
-2x+5y+2z=4
3) -x-5y+z=17
-5x-5y+5z=5
2x+5y-3z=-10
4) 4x+4y+z=24
2x-4y+z=0
5x-4y-5z=12
5) 4r-4s+4t=-4
4r+s-2t=5
-3r-3s-4t=-16
6) x-6y+4z=-12
x+y-4z=12
2x+2y+5z=-15

Solve the system of equations given below. 2x+5y+z= -1, 3x-5y-z=
6, 5x+y+3z= 10.

for 10-12 you will solve the following system of equations:
2x+y+z=-2 2x-y+3z=6 3x-5y+4z=7 10) what is the solution for x? a)2
b)-3 c)infinitely many solutions d)no solution 11) what is the
solution for y? a)2 b)0 c)inifinitely many solution d)no solution
12) what is the solution for z? a)4 b)-8 c)infinitely many
solutions d)no solutions

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.

Solve the system using 3x3
3x-2y+z=2
5x+y-2z=1
4x-3y+3z=7

Solve the following system of equations using matrices(row
operations). If the system has no solution, say that it is
inconsistent.
x + 6y+ 3z = 1
3x - 3y + 3z = 3
4x + 3y + 4z = 4

Use Gaussian elimination with backward substitution to solve the
system of linear equations.
x+y-z=-4
-x-4y+4z=1
-4x-3y+2z=15
What is the solution set?

1. solve the system of equations:
x+3y=9
3x+9y=27
please solve to get the x and y solution
2. solve the system of equations, please state the x and y
solution
9x-4y=23
15x+4y=41
3. solve the system of equations please state the x and y
solution
x - y - z = 1
5x + 6y + z = 1
30x + 25y = 0

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).
