x<-4

Explanation:

Leave the - 2x on the left side of the inequation and collect numeric values on the right side.

add 6 to both sides.

-2xcancel(-6)cancel(+6)>2+6

rArr-2x>8

divide both sides by - 2.

Remember that when we multiply/divide an inequation by a negative value we must color(blue)"reverse the inequality sign"

(cancel(-2) x)/cancel(-2)<8/(-2)larr" reverse sign"

rArrx<-4" is the solution"
