#s = -3/20#

Explanation:

If the question had been:

Solve #5x = 30#, you probably would not have hesitated!

Divide both sides by 5 to isolate the #x#

#(cancel5x)/cancel5 = 30/5#

#x = 6#

This equation is no different.
Divide both sides by 4 to isolate the #s#
The fraction on the right handside is not a problem. Show the division by 4 with a 4 in the denominator.
It means you will divide -3 by 5 and by 4

#(cancel4s)/cancel4 = - \frac { 3} {4xx 5}#

#s = -3/20#
