H/-40+76<77

solve for h

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
-1
H/40>-1

multiply both sides by 40

H>-40

H/-40+76<77

76<77-h/-40

76-77
-1
-40
