Given the statement:

The sum of a number n and 4 is 10.

Determine the value of the sum of n and -1

Solution:

Solve first for n, by equating the given condition in a representation.

n + 4 = 10

To solve for n, we simply need to transpose 4 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

n = 10 - 4

n = 6

Substitute the value of n to the equation n + (- 1)

= 6 + (-1)

= 6 - 1

= 5

Final answer:

The value of the sum of n and -1 is 5
