Question

W=x^2-2yx make y the subject of the formula

Answer 1

`y=(x^2-w)/(2x)`

Explanation:

The given equation is :

w=x²-2yx

We need to find the value of y.

Subtract x² from both sides.

w-x²=x²-2yx-x²

w-x² = -2yx

Dividing both sides by -2x

`(w-x^2)/(-2x)=(-2yx)/(-2x)\\\\y=(w-x^2)/(-2x)\\\\y=(x^2-w)/(2x)`

So, the value of y is equal to
`(x^2-w)/(2x)`.
