Answer 4

\[h+t=162\]\[h=t+62\]\[h-62=t\]\[h+h-62=162\]\[2h-62=162\]\[2h=224\]\[h=112\]

Answer 5

thanks across

Answer 6

polpak got it right before I did, though. ;p

Answer 7

\[h - t = 62\]\[h + t = 162\]
Adding the equations we have:
\[2h = 224\]\[\implies h = 112\]

Answer 8

Yeah, but then I accidentally deleted it ;p

Answer 9
