x = 3
2x + y - z = 3 → (1)
- x + y + 2z = 0 → (2)
3x + 2y + z = 9 → (3)
we require to eliminate the y and z terms from the equations
(1) + (3) : 5x + 3y = 12 → (4)
multiply (1) by 2
4x +2y - 2z = 6 → (5)
(2) + (5) : 3x + 3y = 6 → (6)
(4) - (6) : 2x = 6 ⇒ x = 3
 
        
             
        
        
        
Answer:

Step-by-step explanation:
The formula for the area of a triangle is given by :
 ...(1)
 ...(1)
Where b is the length of the base and h is the height.
We need to find the value of b from the above formula. 
Cross multiplying equation (1) we get :

Now dividing both sides by h. So,

So, the correct option is (D) i.e.  .
.
 
        
             
        
        
        
Answer:
$12,714
Step-by-step explanation:
Loan Amount=$30,000
Monthly Payment =$355.95.
Number of Payment Period = 10 Years X 12 Months =120 Months
Total Payment to be made by Austin =120 X 355.95=$42,714
Therefore:
The interest Austin will pay=Total Payment-Loan Amount
=$42,714-30,000
=$12,714
