Answer 2

Let's simplify the expression step by step:

1.8a - (1.8a - 1.05c) - (1.05c - 0.9a)

First, let's simplify the expression inside the parentheses on the left side:

1.8a - 1.8a + 1.05c - (1.05c - 0.9a)

The two terms 1.8a and -1.8a cancel each other out, leaving us with:

1.05c - (1.05c - 0.9a)

Now, let's simplify the expression inside the parentheses on the right side:

1.05c - 1.05c + 0.9a

Again, the two terms 1.05c and -1.05c cancel each other out, giving us:

0.9a

Therefore, the simplified expression is 0.9a.
