# Mathematics . Simple Linear Equation

Linear Equation in any mathematical equation that has one variable or unknown.

Sample :
X + 5 = 7.
What is the value of x.

In this equation the unknown variable is x.  So we need to solve for x.

X+5 =7
X=7-5
X=2

We must know the rule of inverse when will deal with equation

Note the following rules of inverse
The inverse of + = -
The inverse of * = /  etc

Solve the following
1. 10x + 5 = 8x + 7

2.  X- 4 = 10

3. 2x + 4 = 10

4. 5x + 6 = 3x -  8
