You can, start off with #19s+3(3s-12)#

#28s-36#

#28s-36#

Use the distributive property to get rid of the parentheses first:

#19s+3(3s-12)#

#19s+3*3s-12*3#

#19s+9s-36 rarr 19s# and #9s# can be combined to form one coefficient and a variable

#28s-36#

#28s-36#

Let's first distribute the #3# to the parenthesis to get

#19s+9s-36#

We see we have two #s# terms, so we can combine them to get

#28s-36#

Hope this helps!
