w = -30

Explanation:

Get all the w's to one side of the equation by subtracting 1/2w from both sides.
2/5w = 1/2 w + 3

2/5w- 1/2 w = 1/2 w + 3 - 1/2 w

2/5w- 1/2 w = 3

Simplify the left side by getting common denominators

4/10w- 5/10 w = 3

-1/10 w = 3

Now, divide by (or multiply by the reciprocal of -1/10

-1/10 w * -10 = 3 * -10

w = -30
