Answer 1

Isaiah Anthony

#color(blue)(2w) =P -21 #

#P = 21 + color(blue)(2w#

Isolating #color(blue)(2w:#

#21 + color(blue)(2w) =P #

#color(blue)(2w) =P -21 #

To solve for 2w in the equation P = 21 + 2w, you first subtract 21 from both sides of the equation to isolate the term containing 2w. So, the equation becomes P - 21 = 2w. Then, you divide both sides of the equation by 2 to solve for w. Therefore, 2w = (P - 21)/2.
