#19.32=x#

Set up an equation like this:

#8.4(1.5+2.3)=12.6+x#

where #x# is the missing number:

Solve for #x#:

#8.4(3.8)=12.6+x#

#31.92=12.6+x#

#31.92-12.6=cancel(12.6-12.6)+x#

#19.32=x#

We can verify this by substituting this value for #x# in the original equation and see if everything checks out.

#8.4(1.5+2.3)=12.6+19.32#

You should end up with the same quantity on both sides:

#31.92=31.92#
