Answer:
The numbers are (x,y)=(-5,8) or (8,-5)
Step-by-step explanation:
Let two numbers be x and y,
We have,
x+y=3
x=3-y---(i)
Now,
xy=-40
(3-y)y=-40 [From (i)]
3y-y^2=-40
y^2-3y-40=0
Factoring,
(y + 5) (y - 8)=0
Either,
y+5=0 or, y-8=0
y=-5 y=8
When y=-5,
x=3-y
3--5
3+5
8
When y=8,
x=3-y
3-8
-5

In Carl's use of the standard algorithm of multiplication, the 'y' could represent one of the digits from the correct answer of 14,250 resulting from 2,375 multiplied by 6. Without seeing Carl's actual work, the exact figure for 'y' cannot be definitively determined.
In the question, it appears that Carl is multiplying a number (2,375) by 6 using the standard algorithm for multiplication. Unfortunately, without seeing Carl's work, we can't determine what number 'y' should be. However, if Carl is conducting this multiplication accurately, we can find the result independently to discover what 'y' should be in Carl's equation.
When you multiply 2,375 by 6 using the standard algorithm, you get 14,250. Hence, Carl should find the same answer. For numbers in 'y's place, it seems Carl might be figuring out a digit in the answer. Since we know that the product should be 14,250, if the y is supposed to represent a single digit in Carl's answer, it should be one of these numbers: 1, 4, 2, 5, or 0.
