To solve the equation 7w+5=3w-15, we need to isolate the variable w.

Step 1: Subtract 3w from both sides of the equation.
7w - 3w + 5 = 3w - 3w - 15
4w + 5 = -15

Step 2: Subtract 5 from both sides of the equation.
4w + 5 - 5 = -15 - 5
4w = -20

Step 3: Divide both sides of the equation by 4.
\frac{4w}{4} = \frac{-20}{4}
w = -5

Therefore, the correct answer is w = -5.
