Question

Solve the equation, -(X/ d )=5 , for x . Which of the following properties of equality did you apply

Answer 1

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) \: \: * \: 4 \: \: = - 5 * 4`

Cancellation '4' on left side we get

x = -20

conclusion:-

The solution of given equation x = -20
