Answer:
w = 1/2p -21/2
Step-by-step explanation:
P = 21 +2w.
-21 -21
P - 21 = 2w
/2 /2
1/2p - 21/2 = w
Hope this helps!
Answer:
(P-21)/2=w
Step-by-step explanation:
P = 21 + 2w
Subtract 21 from both sides:
P - 21 = 21 + 2w -21
Simplify:
P - 21 = 2w
Divide both sides by 2:
(P - 21)/2 = 2w÷2
Simplify:
(P-21)/2=w
