What is a System of Equations? And its Solution?
Here is an example of a system of equations (also called a simultaneous system of equations)x2 + y = 3 (1)15x + 3y = 21It's simply a bunch of equations we want to find a single solution for. Though it usually isn't said out loud, the word "and" is always implied:x2 + y = 3 and 15x + 3y = 21.
This means both equations are supposed to be true.
Each equation, by itself, has many solutions. For example, if x = 0 and y = 3 then the first equation is true. But the second equation isn't.On the other hand, if x = 1 and y = 2 , then both equations are true. So we'll say this is a solution of the system.
Let D = 1 denotes the event that an adult male has a particular disease. In the population, it is known that the probability of having this disease is 20 percent, i.e., Pr (D = 1)
We have seen that if y is a function of x, then for each given value of x, we can determine uniquely the value of y as per the functional relationship. For some f
