​

Answer 1

Answer:

Solution:-

• First write the inequality

$\qquad{:}\longrightarrow$$\sf 3x+1 \lt x+5$

• Simplify

$\qquad{:}\longrightarrow$$\sf 3x-x\lt 5-1$

$\qquad{:}\longrightarrow$$\sf 2x\lt 4$

$\qquad{:}\longrightarrow$$\sf x\lt \cancel{\dfrac {4}{2}}$

$\qquad{:}\longrightarrow$$\sf x\lt 2$

$\therefore \bf x\lt 2.$
