It'd be best if you were to enclose that fraction 4/3 inside parentheses:
2>8−(4/3)h
Mult. all 3 terms by 3: 6>24 -4h Add 4h to both sides: +4h +4h ------------------ 7+4h > 24 Subtract 7 from both sides: -7 -7 ------------------ 4h > 17
Then h>17/4 (answer) Note: We want h to be positive. That's why I moved (-4/3)h to the other side of the = sign.
