[tex]3h = 7(\frac{2}{7} -\frac{3}{7}h)-10[/tex]

I've been able to simplify it a good deal but can't figure out how to solve it in the end,... 17 points to you,... thanks,...!

[tex]3h = 7(\frac{2}{7} -\frac{3}{7}h)-10\\[/tex]
Parenthesis Simplification
[tex]3h = 2 -3h-10\\[/tex]
Re-write equation
[tex]3h = 2-10-3h\\[/tex]
Subtract
[tex]3h = -8-3h\\[/tex]
Add 3h to both sides of the equation to take away the "- 3h"
[tex]3h+3h = -8-3h+3h[/tex]
Simplify
[tex]6h = -8\\[/tex]
Divide?
[tex]3h = -4\\[/tex]
Then what?

Thanks for the help,... please answer in full explanation,... Chow!
