`[[x+y+z],[x+z],[y+z]]=[[9],[5],[7]]`

Find the values of x, y and z if {:[(x+y+z),(z+x),(y+z)]={:[(9),(5),(7)]

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 , if [{:(x+y,),(x+z,),(y+z,):}]=[{:(9,),(5,),(7,):}] .

Find the values of x,y and z from the following matrix equations: {:[(x+y+z),(x+z),(y+z)] = [(11),(7),(9)]

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