We can solve the given inequality without using calculator. To do so, we should first gather all of the on one side of the inequality and all of the on the other side using the . In this case, we need to use the . Let's do it!
2x+3<x−1
2x+3−x<x−1−x
x+3<-1
x+3−3<-1−3
x<-4
Solving the inequality algebraically, we also got that each number less than
-4 is the solution of the inequality.
