Answer 1

Step-by-step explanation:

an equation in one variable with one as its highest power is called a linear equation. solving a linear equation there are two methods to solve a linear equation 1 trial and error method 2 systematic method .1 In trial and error method we substitute various values for an unknown value in an equation and finds that particular value for which the value of left hand side becomes equal to value of right hand side in the equation 2 in systematic method the trial and error method becomes lengthy and inconvenient in solving an equation so we use the systematic method to find the solution .
