If P,Q and R are the values of x,y and z respectively, which satisfy the system of equations x+y+z =6,x+2y+3z=14 and x+4y+9z=36, then P+R-Q=

If alpha,beta and gamma are the values of x,y and z respectively which satisfy the system of equations 2x+y+z=1,x-2y-3z=1 and 3x+2y+4z=5, then sin^(-1)((alpha)/(gamma))=

solve the system of equations x+y+z=6,x+2y+3z=14 and x+4y+7z=30 with the help of matrix method.

By crammer's rule,if the values of x,y and z which satisfy the system of equations x+y+z=2 ,x+2y+3z=1 ,and 3x+y-5z=4 are respectively L,M and N then 3L +5M+N=

By crammer's rule ,if the values of x,y and z which satisfy the system of equations x+y+z=2, x+2y+3z=1 ,and 3x+y-5z=4 are respectively L,M and N, then 3L+5M+N=

By matrix inversion method, if the values of x,y and z which satisfy the system of equations,2x-y+3z=9 ,x+y+z=6 and x-y+z=2 are alpha , beta and gamma respectively,then 7 alpha+beta-5gamma

Use matrix to solve the following system of equations. x+y+z=3 x+2y+3z=4 x+4y+9z=6
