3x+y+z=4<br> 2x+2y+3z=3<br> X+3y+2z=5

zhenek [66]

1) 3x+y+z=4
2) 2x+2y+3z=3
3) x+3y+2z = 5

1)*2 6x + 2y + 2z = 8
2) 2x + 2y +3z = 3
- __________________
4x - z = 5

2)*3 6x + 6y + 9z = 9
3)*2 2x + 6y + 4z = 10
- __________________
<span>4x+5z =-1
</span>
4x+5z = -1
4x - z =5
- ________
6z = -6
<u>z = -1
</u><u /><u>
</u>If z=-1,

4x -(-1) =5
4x = 5-1
x = 4/4
<u>x=1</u>

3x+y+z=4
3(1)+y+(-1)=4
3+y-1=4
<u>y=2

So z=-1, x=1, y=2</u>

Solve using any method. All work must be shown and handwritten.

Rashid [163]

Answer:

$x = - 3$

$y = 1$

Step-by-step explanation:

Write the system

$3x - y = - 10$

$x + y = - 2$

Solve by Elimination.

multiply the second equation by -3.

$3x - y = - 10$

$-3x - 3y = 6$

Add the Equations.

$- 4y = - 4$

$y = 1$

Plug this back in one of the equations.

$x + 1 = - 2$

$x = - 3$
