5(2h-6)-7(h=7)>4h
10h-30 - 7h - 49 > 4h
3h - 79>4h
(-3h) +3h - 79 >4h (-3h)
-79 = h

i think thats right. it's been a long time.

(if you plug 19 into the equation you get -2 > 76 which is incorrect)

-79>h. 5 times a -6 and -7 times a 7 adds up to -79.

5(2h-6)-7(h+7)>4h

10h-30-7h-49>4h

combine like terms

-30-49>4h-10h+7h

-79>67h

-1.179>h
