19 and 42 are coprime, so we can use the CRT right away. Start with
Taken mod 42, we're left with a remainder of 19. Notice that
so we need to multiply the first term by 3 to get the remainder we want.
Next, taken mod 19, we're left with a remainder of 4. Notice that
so we need to multiply the second term by 6.
Then by the CRT, we have
so that any solution of the form is a solution to this system.

Answer:
21
Step-by-step explanation:
Dr James ordered 56 pizzas for the teachers.
Of the pizzas ordered, 2/7 of them were pepperoni,
Number that were pepperoni = 2/7 × 56 pizzas
= 16 pizzas were pepperoni
19 were cheese , and the rest were veggie pizzas.
How many of the slices were veggie?
The number of veggie slices is calculated as:
Veggie slices = Total number of pizzas - ( Number of Pepperoni + Number of Cheese)
= 56 - ( 16 + 19)
= 56 - 35
= 21
The number of veggies is 21
