4000 is his total monthly balance.

420 + 380 = 800

800/4000 = 0.20

0.20 = 20%

He spent 20% of his monthly income on food and personal items.

X + y = 13x = 13 - y
2x - 3y = 1

2(13 - y) - 3y = 1
26 - 2y - 3y = 1
-2y - 3y = 1 - 26
-5y = -25
y = -25/-5
y = 5

x + y = 13
x + 5 = 13
x = 13 - 5
x = 8

so, x = 8 and y = 5
