Find the product of 9x, 2y and 5z

Find the product of (5x - y +z) (5x - y +z)

Find the value of x, y and z from the following equations: (i) [(4,3),(x,5)]=[(y,z),(1,5)] (ii) [(x+y, 2 ),(5+z, xy)]=[(6,2),(5,8)] (iii) [(x+y+z),(x+z), (y+z)]=[(9),(5),(7)]

If [{:(x-1," "2,5-y),(" "0,z-1,7),(" "1," "0,a-5):}]=[{:(1,2,3),(0,4,7),(1,0,0):}] then find the values of x , y z and a .

If [(x-1,2,5-y),(0,z-1,7),(1,0,a-5)]=[(1,2,3),(0,4,7),(1,0,0)] then find the values of x,y,z and a.

If [{:(x-1,2,5-y),(0,z-1,7),(1,0,a-5):}] =[{:(1,2,3),(0,4,7):}] then find the values of x,y,z and a.

If [(x-3,2y-8),(z+2,6)]=[(5,2),(-2,a-4)] , then find the values of x,y,z and a.
