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.
Rheumatoid Arthritis. Rheumatoid Arthritis (RA) is an autoimmune disease that afflicts approximately 3% of the population in the U.S. and U.K., mostly women. It is characterised by inflammation of synovial tissues, with joint pain, swelling and stiffness. Although autoimmune arthritis can afflict children and adolescents, the disease usually strikes adults between the ages of 30 and 40, and the incidence of clinical illness is greatest among those aged 40 to 60 years.
