Question

Verify x+(y+z)=(x+z)+z for x=-2,y=-3 and z=7

Answer 1

Step-by-step explanation:

$x + (y + z) = (x + z) + z...(1) \\ x = - 2 \: y = - 3 \: z = 7 \: \: </p><p>put \: the \: value \: </p><p>of \: x \: y \: z \: in \: equaion \: ..(1) \\ => - 2 + ( - 3 + 7) = ( - 2 + 7) + 7 \\ => - 2 + 4 = (5) + 7 \\ = > 2 = 12 \: \: \: \: \\ L. H.S ≠ R.H.S$
