Answer:

$w = \dfrac{k}{3p}$

Step-by-step explanation:

Step 2: Since you want w alone, and w is being multiplied by 3p, divide both sides by 3p.

$w = \dfrac{k}{3p}$

$2x - 6 = 60 - x \\ add \: x \: to \:both \: sides \\ 2x + x - 6 = 60 - x + x \\ 3x - 6 = 60 \\ add \: 6 \: to \: both \: sides \\ 3x - 6 + 6 = 60 + 6 \\ 3x = 66 \\ divide \: both \: sides \: by \: 3 \\ \frac{3x}{3} = \frac{66}{3} \\ x = 22$
