Question 255944
{{{21 + 3h > 6(h-5)}}}

The goal here is to isolate h.  Our first step here is to distribute the 6 through on the right hand side.

{{{21 + 3h > 6h - 30}}}

Next, we subtract 21 from both sides of the inequality:

{{{3h > 6h - 51}}}

Now, subtract 6h from both sides:

{{{-3h > - 51}}}

Last, we divide both sides by -3, remembering that when you divide or multiply by a negative number you have to flip the inequality.

{{{h < 17}}}
