x + l = 6
x – m = 5
x + p = 4
x – q = 3
(x+l)-(x-m)+(x+p)-(x-q)= 6-5+4-3

Let X=0,
Then
l=6
m=-5
p=4
q=-3
So, l+m+p+q=6-5+4-3=2

We can multiply equation 2 by -1 ad equation 4 by -1, and we have:

x + l = 6
-x + m =- 5
x + p = 4
-x + q = -3

Adding these equations together we have:

l + m + p + q = 2
