1. Understand the question

   -9(2 - 3h) = 47h -28

2. Explanation

   Step1: Expand the left side

   Using the distributive property \(a(b - c)=ab - ac\), we have \(-9\times2-(-9)\times3h=-18 + 27h\). So the equation becomes \(-18 + 27h=47h-28\).

   Step2: Move terms with h to one side

   Subtract \(27h\) from both sides: \(-18+27h - 27h=47h-28 - 27h\), which simplifies to \(-18 = 20h-28\).

   Step3: Solve for h

   Add 28 to both sides: \(-18 + 28=20h-28 + 28\), so \(10 = 20h\). Then divide both sides by 20: \(h=\frac{10}{20}=\frac{1}{2}\).

3. Final answer

   \(h = \frac{1}{2}\)
