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.

[tex]3w + 2 = 7w[/tex]
[tex]3w + 2 = 7w:w[/tex] [tex]|Solve \ for \ w|[/tex]
[tex]2=7w-3w[/tex] [tex]|Subtract \ 3w \ from \ both \ sides|[/tex]
[tex] 2=4w [/tex]
[tex] \dfrac{2}{4}=w [/tex] [tex]|Divide \ both \ sides \ by \ 4|[/tex]
[tex]w= \dfrac{1}{2} [/tex]
