Introduction to linear relationships online help:

Linear relationship is nothing but the function varies directly with the input. The graph of linear relationship is a straight line. Linear relationships include linear equations and systems of linear equations with some unknowns. All the points lie on a line then such a model is called a linear relationship because it represents a straight line relationship between the points. Through the online help, student can get clear idea about how to solve linear relationships. Now, we are going to see some of the problems on linear relationships online help.

Example :

Solve the linear relationship in the equation: -2(y + 3) = y + 9

Also find more help linear programming example

Solution:

-2(y + 3) = y + 9

First we need to eliminate the parentheses

-2y - 6 = y + 9

Add 6 to both sides of the equation

-2y - 6 + 6 = y + 9 + 6

-2y = y + 15

Subtract y on both sides of the equation

-2y - y = y + 15 - y

-3y = 15

Divide-3 on both sides of the equation Learn solving math Online

y = -5

y = -5 is the solution to the given equation.
