+2972 Very interesting question indeed
7x+4>18
i know what x can only mean
x can only equal at a minimum of 3
If x=1
7x=7+4=11>18. <-Statement false
if x=2
7x=14+4=18>18 <- again statement false
if x=3
7x=21+4=25>18<-finally statement true
so X overall has to be a minimum of 3 if you want 7x+4>18 to be a true statement
