Hello!
To solve the inequality, you'll need to multiply 7 with x and -2. Once you've done that you'll be one step closer to solving.
7x-14<-5
Next, you'll need to add 14 to -5. Once you have that done, -5 should now be 9.
7x<9
Now you need to divide both sides by 7. Once you've done that you'll have an inequality of...
x< 9/7
I hope this helps!
