The sum of a number n and 4 is 10. What is the value of the sum of n and - 1?

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

Step-by-step explanation:

Step 1

Get the value of n using the equation below;

The sum of n and 4 is 10 can be expressed in equation form as follows;

n+4=10 ... equation 1

solving for n;

n=10-4

n=6

The value for n=6

Step 2

Express the sum of n and - 1 as follows

n + (-1) = unknown ... equation 2

using the value of n solved in equation 1 in equation 2

replace using;

n=6

6 + (-1) = 6-1=5

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