You reduce the scale like a fraction
First you have to get the same variables on one side so you’d subtract 5.1w from both sides, making the equation -0.6w = -30
then you want to single out the variable, diving -0.6 on both sides making the new equation and the answer w = 50
hope this helps!
8.64 - 3.15 = $5.49 if this is what you are asking
The answer is 40 is 80% of 50 ☺
