Simple Linear Equations in One Variable with Two Operations

 

About

When there is just one variable in the equation which has an exponent of 1, it is known as Linear equation.

Example:  

15x = x–7

In order to solve linear equations we need to isolate the variable

Demonstration

1) One step operation

Y - 3 = 15

Solution:

This time, 3 is being subtracted from y. So, we will undo that by adding 3 to both sides.

Y – 3 + 3 = 15 +3

Y = 18

 

2) Two Step Operation

5x - 2 =15

Solution:

Adding 2 to both sides:

5x - 2 =15

5x -2 + 2= 15+2

5x =15

Now divide both sides by 5

 5x /5= 15/ 5

X=3
