The information given:

a+b=8 (the sum of two numbers is 8)

b=a-6 (one number is 6 less than the other)

Since we have two equations and two variables, we can substitue one equation on the other:

a+(a-6)=8

a+a-6=8

2a-6=8

2a=8+6

a=14/2

a=7

Since we have a, now we substitute a in the equation:

7+b=8

b=8-7

b=1
