19.32=x19.32=x

Explanation:

Set up an equation like this:

8.4(1.5+2.3)=12.6+x8.4(1.5+2.3)=12.6+x

where xx is the missing number:

Solve for xx:

8.4(3.8)=12.6+x8.4(3.8)=12.6+x

31.92=12.6+x31.92=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
