See explanation

#### Explanation:

We must use the PEMDAS method. Let's solve for the parentheses first:

$3 + 12 = 15$
$23 - 4 = 19$

We now have $5 \left(15\right) + 42 \left(19\right)$

Next is multiplication:

$5 \cdot 15 = 75$
$42 \cdot 19 = 798$

$75 + 798$

From here, it's simple addition: $75 + 798 = 873$
