Best ResponseYou've already chosen the best response.0if we define x in terms of y and z, we can use that in the other 2 equations ... and it reduces to a system of 2 equations

Best ResponseYou've already chosen the best response.1ok see lets use elimination method.....we will eliminate "x" x + 2y  z = 3 > say 1st equation 2x  2y + 2z = 8 which is also x  y + z = 4 > say 2nd equation 2x  y + 3z = 9 > say 3rd equation

Best ResponseYou've already chosen the best response.1now multiply 2nd equation from 1 and add the new equation with 1st equation..... "x" gets eliminated...... did u understand??

Best ResponseYou've already chosen the best response.1hmmmmmmm _ wht u did ???? i askd to eliminate "x" the 1st equation is x + 2y  z = 3 and when u multiply 2nd equation from 1 u get x + y  z = 4now add these two equations
