Solve for x and y: x+y=a+b, ax-by=a²-b²

  • 0

This is the basic and conceptual question from linear equations in two variables as it was already asked in various examinations in which we have given two equations x+y=a+b, ax-by=a²-b² and we have to find the value of variables x and y from the given equations

Kindly give me a detailed solution of this question

  1. a(x+y)=a(a+b)

    ax+ay=+ab.........(1)

    axby=........(2)

    (1)(2) gives
    (a+b)y=b(a+b)y=b

    Hence, From (1) x=a
