Answer:
hello the system related to your question is missing below is the system
–3x + y – 2z = 10 --------(1)
5x – 2y – 2z = 12 -------- (2)
x – y + z = 23 ----------- (3)
answer :
To reduce the system above to a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires X and either Y or Z
Step-by-step explanation:
Given system :
–3x + y – 2z = 10 --------(1)
5x – 2y – 2z = 12 -------- (2)
x – y + z = 23 ----------- (3)
To reduce the system above to a 2 * 2 , I would eliminate either Y or Z from the system because a 2 * 2 system requires X and either Y or Z
Eliminating X is not the best way
<em>solving equation 1 and 2 </em>
substrate equation (1 ) from equation (2) to eliminate Z
= 8x - 3y = 2
multiply equation (3) by 2 then substrate equation (2) from (3) to eliminate Y
2x - 2y + 2z = 46
-( 5x - 2y - 2z )= 12
= -3x + 4z = 34
Answer:
Step-by-step explanation:
Three forces A, B and C pull on ropes tied to a ring such that ring is in equilibrium.
For the ring to be in equilibrium the force must be concurrent i.e. there line of action must be passed through a single point.
There is no net force when forces are concurrent.
When all three forces are equal then they should be at angle of to each other.
