Question #4663e

Answer 1

`19.32=x`

Explanation:

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`
