Answer:
For the first one, it is 1150. For the second one, it is 2460.
Step-by-step explanation:
Think of 23 x 50 as (20 x 50) + (3 x 50).
20 x 50 is 1000. 3 x 50 is 150. 1000 + 150 is 1150.
Think of 30 x 82 as (30 x 80) + (30 x 2)
30 x 80 is 2400. 30 x 2 is 60. 2400+60 is 2460.

Answer:
the two numbers are 14 and 19
Step-by-step explanation:
x + y = 33
x - y = 5 ⇒ x = y + 5
substitute x = y + 5 in x + y = 33
y + 5 + y = 33
2y + 5 = 33
2y = 33 -5
2y = 28
y = 28/2
y = 14
x = 14 + 5
x = 19
