Kramer's Rule 2x+7Y=-4 
                       X+4+-3  how is it done

You can do the simultaneous equation.  Do this multiply the second equation by 2 getting:      2x+8y=-6,   then subtract  the first equation
                  2x+7y=-4
                          y = -2

x would be 5

Sorry you wanted to use matrice, that was not Cramer's Rule lol.   But for only 2 or 3 linear equations, it would suffice.  suggest you google cramers rule.
