Explanation:
first u gotta make the solutions on the other side a negative then keep the positive so now you've gotten rid of the lines so now I gotta solve both 4x-3<7 and 4x-3<-7 then solve liek you regular would with moving the 3 to the other side
4x<10 and 4x<-4 then divide both of them by the number itself to get x by itself
