Question

Solve the equation, –(x∕4) = 5, for x. Which of the following properties of equality did you apply? Question 7 options: A) Multiplication B) Multiplication and subtraction C) Division and addition D) Division

Answer 1

Answer:

A) Multiplication

The solution of given equation  x= -20

Step-by-step explanation:

Step(i):-

Given equation  - ( x /4) = 5

Multiply '-1' on both sides, we get

                     ⇒    - ( (- x /4) ) = - 5

                     ⇒    $\frac{x}{4} = -5$

Step(ii):-

Multiply '4' on both sides, we get  

                     ⇒    $\frac{x}{4} X 4= -5 X 4$

Cancellation '4' on left side , we get

                          x = -20

Conclusion:-

The solution of given equation  x= -20
