Show that the following systems of equations has a unique solution and solve it: 3x+5y=12, 5x+3y=4

  • 0

This is the basic and conceptual question from linear equations in two variables in which we have given two equations 3x+5y=12, 5x+3y=4  and we have been asked to solve the given equations in such a way that it has a unique solution

Kindly solve the above equations

  1. The equations are given as,

    3x+5y=12

    And,

    5x+3y=4

    Dividing the same coefficients and comparing,

    3/5≠5/3

    Since, the coefficients of x and y are not equal, therefore, the given system of equations has a unique solution
