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