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
