Solving a System of 2 Equations Using the Addition/Subtraction Method
To solve a system of linear equations using the addition/subtraction method, both equations should first be written in the form Ax + By = C.
Let's take a look at the system of equations below:
x + 2y = 3
15x - 2y = 29
As shown below, adding the equations together eliminates one of the variables. In this case, it's the y-variable that is eliminated.. Now we're left with 16x = 32. Solving for x, we get x = 2.
Substitute 2 for the x-variable in either of the original equations and solve for y. (We'll use the equation x + 2y = 3 because it looks simpler.)
x + 2y = 32+2y = 32y = 1Y = 1/2So we claim that the solution to the system is (2, 1/2) Now check this answer in both of the original equations: Therefore, the solution to the system is (2, 1/2)

How to find a function
Rates of Change and Tangent Lines : In this section we will study two fairly important problems in the study of calculus. There are two cause for looking at these problems now.
Q. Define natural numbers Ans. The natural numbers (also called the counting numbers) are the numbers that you "naturally" use for counting: 1,2,3,4,... The set of n
Let E; F be 2 points in the plane, EF has length 1, and let N be a continuous curve from E to F. A chord of N is a straight line joining 2 points on N. Prove if 0 Prove that N ha
Level Curves or Contour Curves Another topic that we should look at is that of level curves or also known as contour curves. The level curves of the function z = f (x, y) are t
