If `x,y,z in R & Delta =|(x,x+y,x+y+z),(2x,5x+2y,7x+5y+2z),(3x,7x+3y,9x+7y+3z)|=-16` then the value of x is

If x,y and zinR , and Delta=|(x,x+y,x+y+z),(2x,5x+2y,7x+5y+2z),(3x,7x+3y,9x+7y+3z)|=-16 , then find value of x.

if 2x+3y-3z=0;5x-2y+2z=19;x+7y-5z=5. Then the value of x+y-z is

If (x,y,z) is the solution of the equations 4x + y = 7 3y + 4z = 5 5x + 3z = 2 Then the value of x + y + z equals

If [[x+y+z],[x+z],[y+z]] = [[9],[5],[7]] ,then the value of x-y+z is

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

3x+4y+7z=4, 2x+y+ 3z= 3, x + 2y +3z =8.

If ({:(3x -y, x + 3y),(2x - z, 2y +z):}) = ({:(7,9),(5,5):}), then x + y + z equals

Add 2x - 3y + z , 5y - x + 7z and 3x - y - 6z.
