Question

Make y the subject of the formula

Answer 1

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

Explanation:

Given:

w = x² - 2yz

Required:

Solve for y

Solution:

`w = x^2 - 2yz`

Subtract x^2 from not sides

`w - x^2 = - 2yz`

Divide not sides by -2z

`(w - x^2)/(-2z) = (-2yz)/(-2z)`

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

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