We select the symbol of '<' if we assume temporarily for 4x+3 12.
Assume temporarily for 4x+3 12, we select the symbol of '<' because the real equation is "4X+3>12" in which the symbol '>' is used. The symbol '>' is used to show the greater number and a smaller number. The pointed side shows that the number is smaller.
while on the other hand, the wider part shows that the number or value is greater than the other one so we can conclude that we select the symbol of '<' if we assume temporarily for 4x+3 12.
