2(3 + 9x) - 2x

= 6 + 9x - 2x <----------------mistake right here

= 6 + 7x

Correct:

Expanding by using distributive property

2(3 + 9x) - 2x

= 2* 3 + 2 * 9x - 2x

= 6 + 18x - 2x

= 6 + 16x

Please solve for w, p=21+2w
sp2606 [1]

Answer:

w = (p - 21)/2

Step-by-step explanation:

Rearrange the equation so that it is equal to w.

p = 21 + 2w

p - 21 = (21 + 2w) - 21

p - 21 = 2w

(p - 21)/2 = (2w)/2

(p - 21)/2 = w

w = (p - 21)/2
