Solving Linear Equations

Topic:- Linear Equation


A mathematical expression that has an equal sign and linear expressions is called a Linear equation.

A number that you don't know,often represented by "x" or "y" is called a variable.

We solving linear equations by clicking and dragging a number to the "other" side of the equal sign. Remember that you are "isolating" the unknown "X" to solve the problem.
(Example is provided below.)

Question:-

Solve 2x-18=15
Answer:-

This math help is a part of linear equations.

2x-18=15

Add 18 to both sides

2x-18+18 = 15 + 18

2x = 15+18

2x = 33


divide by 2 on both sides


2x      33
----- = -------
2        2


  x = 16.5

16.5 is the Answer.
