Answer 1

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

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
