When is solved for w, one equation is Which of the following is an equivalent equation to find w?

B w = 8x^2-2y / y

The answer is w = 8x^2-2y / y

Step-by-step explanation:

The complete question is:

When 2x^2/y = w+2/4 is solved for w, one equation is w = 8x^2/y - 2 Which of the following is an equivalent equation to find w?

w = 8x^2+2y / y

w = 8x^2-2y / y

w = 8x^2 - 3y

w = 8x^2 - y

Now we will find the solution.

We have to solve for w, therefore it shows that we have to isolate w.

We can do this like this:

We have:

2x^2/y = w+2/4

First we will perform cross multiplication.

We get,

4 (2x^2) = y (w+2)

8x^2 = wy+2y

Now isolate the w.

8x^2-2y = wy

Divide both sides by y

8x^2-2y / y = wy/y

8x^2-2y/y = w

w = 8x^2-2y / y

Thus the correct answer is:

w = 8x^2-2y / y ...
