LINEAR EQUATION

-1 example for every term

Types of Solution

1. Consistent

2. Inconsistent

PARAMETER
- specific sample out of the population

CONSISTENT Sample

1 solution

x+y=2

x-y=1

Infinite Solution

2x+2y=2

4x+4y=4

INCONSISTENT Sample

x+y=5

x+y=7

To limit the infinite solution

ex.

x1+2x2=4

x1= 4-2x2

x2= t, t is a whole number

x1= 4-2t
