Linear Equations in One Variable


   
 
Summary
A solution of a linear equation is the value of the variable which makes LHS = RHS. It is also called the "root" of the equation.
 
To solve a linear equation, we transpose all the terms containing the variable to one side and the constant terms to the other. The equation then reduces to the form ax = b.
 
The solution is
 
To form an equation from a given statement, we replace the unknown by x and express the given condition algebraically.
