Answer 1

Answer:

Answer:

• The equations has unique solution.

Given:

The equations are

→ 2x+3y+3z=5

x-2y+z=-4

3x-y-2z=3

Solution:

Since,

The given equations are

$2x + 3y + 3z = 5$

$x - 2y + z = - 4$

$3x - y - 2z = 3$

solve equation 1 & 2

Multiply equation 2 with '2'.

$7y + z = - 3$

Now, Solve equation 2&3.

$5y - 5z = 15$

$y - z = 15$

These two equations are in the form,

$lx + my = p$

$ax + by = q$

So,It has unique solution.
