|
Answer» Solution :5x + 7 `lt` 32 `rArr 5x+7-7 lt 32-7` `rArr 5x lt 25` `rArr (5x)/5 lt (25)/5` `rArr x lt 5` If x `in` Z then the solution set isS = {x:x `in` Z and x `lt` 5} ={……. -3,-2,-1,0,1,2,3,4} If x is a NON negative solution then the solution set is S = { x: x is a non negative INTEGER `lt` 5} = {0,1,2,3,4} |
