First off what ummmmmm section of mathmatics are you doing?
Answer:
Step-by-step explanation:
Given system is-
-2x+2y+3z=0 -------------(1)
-2x-y+z=-3 ----------------(2)
2x+3y+3z=5 --------------(3)
From (1)-(2) we get
3y+2z=3 ----------------(4)
Again from (2)+(3),
2y+4z=2 ----------------(5)
Now multiplying equation (4) by -2
-6y-4z=-6 --------------(6)
Adding (5) and (6)
-4y=-4
dividing by -4
y=-4 / -4
=1
So, y=1 ,
using y=1 in (5)
2(1)+4z=2
or, 2+4z=2
or, 4z=2-2
or, 4z=0
or, z=0
using y=1 and z=0 in (3)
2x+3(1)+3(0)=5
or, 2x+3+0=5
or, 2x=5-3
or, 2x=2
or, x=2/2
=1
So, the solution is-
(x,y,z)=(1 , 1 , 0)

The type of cutting oil used in machining operations is called soluble oil.
<h3>What are cutting oils?</h3>
Cutting oils is a kind of coolant and lubricant particularly made for metal working processes. Machines like hand-cutting machinery are utilized with it cutting oils.
The most popular and least expensive form of cutting fluids oils used in machining processes are soluble oils. They have average lubricating qualities and good cooling abilities. They work best for small-scale cutting activities.
