Question

Sole for y
k = p/2(y+w)
y =

Answer 1

`\pi {y}^( \alpha \: so \: y = k)`

Answer 2

Answer: y = (2k -pw)/p

Explanation:

`k = (p)/(2) (y + w)`

multiply 2 on both sides:

`k * 2 = 2 * (p)/(2) (y + w) \\ \\ 2k = p(y + w)`

open the bracket:

`2k = py + pw`

subtract pw from both sides:

`2k - pw = (py + pw) - pw \\ 2k - pw = py`

divide p on both sides:

`(2k - pw)/(p) = (py)/(p) \\ \\ y = (2k - pw)/(p)`
