Question

Verify: [-x- (-y)] -z=-x-[-y-(-z) ] where x= 28,y=-12, z=27​

Answer 1

Answer:

LHS = RHS = -67

Step-by-step explanation:

It is given that

x = 28, y = -12, z = 27

To verify:

[-x- (-y)] -z=-x-[-y-(-z) ]

LHS:

[-x - (-y)] - z = { -28 - [-(-12) ] } - 27      

= (-28 - 12) - 27 = -40 - 27 = -67

RHS:

-x-[-y-(-z) ] = -28 - [-(-12) - (-27)]

= -28 - [12+27] = -28 - 39 = -67

LHS = RHS

Hence Verfied
