Fill in the blanks to make the following statements true:

(i) (–5) + (– 8) = (– 8) + (…………)​

Answer 1

Fill in the blanks to make the following statements true:

(i) (–5) + (– 8) = (– 8) + (…………)

Solution:-

⚛Let us assume the missing integer be x,

Then,

= (–5) + (– 8) = (– 8) + (x)

= – 5 – 8 = – 8 + x

= – 13 = – 8 + x

⚛By sending – 8 from RHS to LHS it becomes 8,

= – 13 + 8 = x

= x = – 5

⚛Now substitute the x value in the blank place,

(–5) + (– 8) = (– 8) + (- 5) … [This ⚛equation is in the form of Commutative law of Addition]
