-Take the second equation and divide all terms by 3.-This gives us two equations set up as "y = mx+C" -Make the equations equal to each other as Y = Y at the point of intersection.-Solve from here.

Step 1) 2x + y = 18 (a) Step 2) x - y = 6 (b) Step 3) using (a): y = 18 - 2x (c) Step 4) using (b): y = x - 6 (d) Step 5) Combine (c) and (d): 18 - 2x = x - 6 (e) Step 6) Rearange (e) to find x: 3x = 24 --&g...

Diffusion is the passive movement of particles from an area of high concentration to an area of low concentration. Factors which affect it include temperature , the concentration gradient , the surface area ...

ADH, short for antiduretic hormone, is produced when the concentration of solutes in blood plasma increases - this is detected by receptors in the brain. ADH is then released into the bloodstream, where it r...

During inspiration the diaphragm contracts flattening, and the external intercostal muscles contract pushing out the ribs and sternum. This increases the volume and decreases the pressure within the thoracic...
