Given,
First applying matrix addition then, comparing each element of the
matrix with the corresponding element we get,
We now have, x + 4 = 3x, .....(i)
x = 2
2w + 3 = 3w, .......(ii)
w = 3
6 + x + y = 3y, substituting x from (i) we get,
y = 4,
And -1 + z + w = 3z, substituting w from (ii), we get,
z = 1
