Solve the system using the elimination method. 3x-2y=15 x+_y=0

x = 3, y = -3

Step-by-step explanation:

3x - 2y = 15   (eq 1)

x + y = 0        (eq 2)

(eq 2) x 2

2x + 2y = 0    (eq 3)

(eq 1) + (eq 3)

5x = 15

x = 3

SUB x=3 into (eq 2)

3 + y = 0

y = -3

Order of steps are as follow;

1. In mechanical digestion, the teeth grind food and break it in to smaller parts.

2.Churning and enzyme pepsin break down protein in the stomach.

3. The pancreas releases the enzyme trypsin and chymotrypsin.

4. Amino acids are absorbed by the capillaries in the jejunum

5. Amino acids enter the bloodstream and are then circulated throughout the body.

Basically this says, food with source of protein is digested mechanically in your mouth, small pieces are then further broken down in the stomach through enzymatic action pepsin and those that are secreted by the pancreas, further absorbed by capillaries and circulated throughout the body via blood.
