Depends.

Do you mean %289%2F2%29h=-1 or 9%2F%282h%29=-1?

If the former, just multiply by the reciprocal of the fraction:

%282%2F9%29%289%2F2%29h=-1%2A%282%2F9%29
h=-2%2F9

If the later, multiply both sides by 2h

%289%2F%282h%29%29%2A2h=-1%2A2h
9=-2h

Then divide both sides by -2

9%2F-2=h

If the problem is 9%2F%282h%29=-1,
9%2F%282h%29=-1
9%2F%282h%29%2A%282%2F9%29=-1%2A%282%2F9%29 multiply both sides by 2/9
1%2Fh=-2%2F9 simplify
h=-9%2F2 invert
If the problem is 9%2F2%2Ah=-1,
9%2F2%2Ah=-1
9%2F2%2Ah%2A%282%2F9%29=-1%2A%282%2F9%29 multiply both sides by 2/9
h=-2%2F9 simplify
