Question

Given the equation P = 2w + 21 solve for w.

Answer 1

p = 2w + 21

Subtract 21 from both sides

p - 21 = 2w

Divide 2 to isolate the w

(p - 21)/2 = w

Answer 2

Hello :)

first switch p to the other side

2w + 21 = P

Subtract 21 from both sides

2w + 21 = P

-21 -21

2w = P - 21

divide both sides by 2

`\\(2w )/(2) = (P-21)/(2)`

lastly, simplify

`w=(P-21)/(2)`
