Answer:

  a = 2.4

Step-by-step explanation:

The problem statement tells you ...

  b/a = 6

  b - a = 12

Using the first equation, we can write an expression for b:

  b = 6a . . . . . . . multiply both sides by "a"

This can be substituted into the second equation to find a value for "a":

  6a -a = 12

  5a = 12

  a = 12/5 = 2.4

The value of a is 2.4.
