Respuesta :

x<1 Because everything less than 1 multiplied by 3 will be less than 3

Answer:

S={x∈R|x<1} or (-∞,1)

Step-by-step explanation:

Hi there, In this inequality we have to find out the Solution Set defined within the Real Set

[tex]3x <3\\ \frac{3x}{3} <\frac{3}{3}  \\ x<1\\[/tex]

S={x∈R|x<1} or (-∞,1)
