Question

Determine the integer whose product with -1 is
(a) 1
(b) -21
(c) 44
(d) 0
(e)-1​

Answer 1

Answer:

-22 is the integer

Step-by-step explanation:

Divide both sides of the equation by -1

1. ⇒(−1)×x(−1)=−22(−1}

We can write the above equation as

⇒(−1)×x(−1)=22×(−1)(−1)

Cancel same factors from numerators and denominator on both sides of the equation

⇒x=22

We check if the value obtained is integer or not if it lies in the set of integers i.e.Z={...−3,−2,−2,0,1,2,3...}

.

Since 22 lies in Z, so 22 is an integer.

∴

The value of integer is 22.
