Respuesta :
H/-40+76<77
Assume no parentheses missing, then
subtract 76 from both sides
H/(-40)+76-76<77-76
H/(-40)<1
-H/40 < 1
either change sign on both sides and switch direction of inequality, or
add H/40-1 to both sides, latter gives
H/40-H/40-1<H/40+1-1
-1<H/40 or
H/40>-1
multiply both sides by 40
H>-40
