    8x + 3y = -21.....(1)
    4x + 5y = - 7......(2)
    The basic idea is to solve for the values of 'x' and 'y'.
    The first step is to find the value of 'x' or'y' (but not both) by eliminating either
    'y'or 'x' (but not both).
    >Let us assume that we want to eliminate 'x'.
    >In equation (1), there are 8x's and in equation (2) there are only 4x's. To eliminate 'x' we need to make the number of ...
