Answer 2

To solve the expression, we'll combine like terms:

7a - 5a - 1.3a

Step 1: Combine like terms with 'a': (7a - 5a - 1.3a) = (7 - 5 - 1.3) * a

Step 2: Perform the arithmetic on the constants: (7 - 5 - 1.3) = 0.7

Step 3: The simplified expression is: 0.7a

So, the solution to the expression is 0.7a.
