So this is actually composed o 2 sentances 20x-18<50 AND 50<36x-16 so solve each and find solutions where x is the same in both sentances 20x-18<50 add 18 to both sides 20x<68 divide both sides by 20 x<3 and 2/5 then the second sentance 50<36x-16 add 16 to both sides 66<36x divide both sides by 36 1 and 5/6<x so since it is and, combine 3 and 2/5>x>1 and 5/6 or 17/5>x>11/6
