Jack is thinking of two whole numbers the sum of the number is 13
the difference between the numbers is 1
what is the product of the numbers

The product of the two numbers will be 42.

Let the two numbers be A and B

A + B = 13

A - B = 1

A = 1 + B.

Therefore, since A + B = 13, then (1 + B) + B = 13

1 + 2B = 13

2B = 13 - 1

2B = 12

B = 6

A = 6 + 1 = 7

Since the numbers are 6 and 7, then multiplying them is 42.

Their product is 42

Step-by-step explanation:

Let the numbers be A and B

Such that:

Required

Determine A * B

Add both equations together:

Solve for A

Substitute 7 for A in the second equation

Make B the subject

Hence,

A = 7 and B = 6

So:

The answer is -2.

You put the 4 in for the x and solve.

4 x 2 = 8

8 - 10 = -2
