Find the value of x, y, z if
`((x-3, 3x-z), (x+y+7, x+y+z))=((1, 0), (1, 6))`

Find the value of x, y, z if [(x, y-z, z+3)]+[(y, 4, 3)]

Find the values of x, y, z if the matrix A=[(0, 2y,z),(x,y,-z),(x,-y,z)] satisfy the equation A'A=I .

Find the values of x, y, and z from the following equations [(x+y+a), (x+z), (y+z)]=[(9), (5), (7)]

Find the values of x, y, and z from the following equations [(12, 3), (x, 5)]=[(y, z), (3, 5)]

Find the value of |(1,log_(x) y,log_(x) z),(log_(y) x,1,log_(y) z),(log_(z) x,log_(z) y,1)| if x,y,z ne 1

The value of x + y + z is 15. If a, x, y, z, b are in AP while the value of (1)/(x) + (1)/(y) + (1)/(z) " is " (5)/(3) . If a, x, y, z b are in HP, then find a and b .
