From the given equation, we can see that -10 = 2k, -w^2 = -64, 2f = -20, and 3 = 3.
From the first equation, 2k = -10, we can solve for k by dividing both sides by 2: k = -5.
From the second equation, -w^2 = -64, we can solve for w^2 by multiplying both sides by -1: w^2 = 64. Then we can take the square root of both sides to find w: w = ±8.
From the third equation, 2f = -20, we can solve for f by dividing both sides by 2: f = -10.
Thus, the values of the variables are k = -5, w = ±8, and f = -10.
Find the values of the variables.
