Linear equation is the equation in which all the variables have exponent equal to 1. Lets take an example of linear equation . In this equation, we have just one variable and we can clearly notice that exponent of is 1. Similarly we can write few more examples of linear equations:
Formulate the following problems as a part of equations, and hence find their solutions.
Solve the following pairs of equations by reducing them to a pair of linear equations:
Form the pair of linear equations in the following problems and find their solutions (if they exist) by any algebraic method:
