Answer 1

A

Explanation:

Answer 2

A) Multiplication

The solution of given equation x= -20

Explanation:

Step(i):-

Given equation - ( x /4) = 5

Multiply '-1' on both sides, we get

⇒ - ( (- x /4) ) = - 5

⇒
`(x)/(4) = -5`

Step(ii):-

Multiply '4' on both sides, we get

⇒
`(x)/(4) X 4= -5 X 4`

Cancellation '4' on left side , we get

x = -20

Conclusion:-

The solution of given equation x= -20
