Step 1. Cancel 3 on both sides
0 = -2|14s - 5|
Step 2. Divide both sides by -2
0 = |14s - 5|
Step 3. Drop the absolute value, since this equation sums to zero
0 = 14s - 5
Step 4. Solve the first equation: 0 = 14s - 5
s = 5/14

[tex]\mathrm{Subtract\:}3\mathrm{\:from\:both\:sides}\\3-3=-2\left|14s-5\right|+3-3\\Refine\\0=-2\left|14s-5\right|\\Switch\:sides\\-2\left|14s-5\right|=0\\\mathrm{Divide\:both\:sides\:by\:}-2\\\frac{-2\left|14s-5\right|}{-2}=\frac{0}{-2}\\Simplify\\\left|14s-5\right|=0\\|f\left(s\right)|=\:0\quad \Rightarrow \:f\left(s\right)=0\\14s-5=0\\Answer: s=\frac{5}{14}[/tex]
