As you can see the solution to the system is the coordinates of the point where the two lines intersect. So, when solving linear systems with two variables we are really asking where the two lines will intersect. We will be looking at two methods for solving systems in this section.
Rheumatoid arthritis (RA) is an autoimmune disease in which the bodyâs immune system mistakenly attacks the membranes that line the bodyâs joints. The result is inflammation and pain in the joints.RA is a chronic disease that can cause periods of intense activity called flare-ups.esearchers have established that certain genetic markers may increase your risk of developing RA. The genes in question are related to the immune system in general, to chronic inflammation, or with RA in particular. It is important to note that not everyone with these markers develops RA.
