|To find the solution of an equation, you may try all the values from the domain of a variable one at a time. However, it would be time consuming. Instead, you can guess the value of the variable for which the equation will be satisfied, i.e., LHS and RHS become identical.
Example: Solve 2x+4 = 62, where x is an integer.
By observing the equation, you could see that the equation may be satisfied for a value of x around 30. Therefore, you may try x=29, 30, or 31. By trying these guessed values, you can verify that the root of the above equation is 29.
