If [{:(,x+3,z+4,2y-7),(,-6,a-1,0),(,b-3,...

If `[{:(,x+3,z+4,2y-7),(,-6,a-1,0),(,b-3,-21,0):}]=[{:(,0,6,3y-2),(,-6,-3,2c+2),(,2b+4,-21,0),(,2b+4,-21,0):}]` then find the values of a,b,c,x,y and z.

Text Solution

Verified by Experts

As the given matrices are equal. Therefore, their, corresponding elements must be equal. Comparing the corrsponding elements, we get
`{:(,x+3=0,z+4=6,2y-7=3y-2),(,a-1=-3,0=2c+2,b-3=2b+4):}`
`Rightarrow a=-2,b=-7,c=-1,x=-3,y=-5,z=2`
