Step-by-step explanation:
{โ2x + 2y + 3z = 0
{โ2x - y + z = โ3 โ
{2x + 3y + 3z = 5 โ
2y + 4z = 2 โท
{โ2x + 2y + 3z = 0 โ
{โ2x - y + z = โ3
{2x + 3y + 3z = 5 โ
5y + 6z = 5 โท
{5y + 6z = 5
{2y + 4z = 2
โโ
[5y + 6z = 5]
{โ2y - 2โ
z = โ2 >> New Temporary Equation
{2y + 4z = 2
____________
1โ
z = 0
___ _
1โ
1โ
[Plug this back into both equations above to get the y-term of 1, then plugging both z-term and y-term into all three equations at the very top, will give you the x-term of 1]; ;
