A number = x

x divided by 7 = x/7

is less than = <

-3 = -3

You're question is: x/7 < -3

Simplify it. Isolate the x. Multiply 7 to both sides

(x/7)(7) < (-3)(7)

x < (-3)(7)

Simplify, multiply.

x < -21

x < -21 is your answer

First let's write this: x/7<-3

To get rid of /7 we need to multiply by seven, so we do -3*7; which is -21

Bring down the symbol and you have x<-21

Anything less than -21, for example -28, would solve the inequality.
