Question

3w + 2 = 7w Please help

Answer 1

3w +2 =7w
-3w       -3w
2=4w
Divide each side by 4
1/2=w

Check your answer:
3 (1/2) + 2 = 7 (1/2)
(3/2) + (4/2) = (7/2)
(7/2) = (7/2)

Hope this helps.

Answer 2

$3w + 2 = 7w$ 

$3w + 2 = 7w:w$  $|Solve \ for \ w|$ 

$2=7w-3w$   $|Subtract \ 3w \ from \ both \ sides|$

$2=4w$ 

$\dfrac{2}{4}=w$   $|Divide \ both \ sides \ by \ 4|$

$w= \dfrac{1}{2}$
