Explanation:

Let's break down the expression step-by-step:

- First, simplify inside the parentheses: \(0.2 ÷ 0.5 = 0.4\).

- Next, \(0.3 - 0.4 = -0.1\).

- Continue with the outer parentheses: \(1.1 - 0.3(-0.1) = 1.1 + 0.03 = 1.13\).

- Multiply by 0.9: \(0.9 \times 1.13 = 1.017\).

- Divide by 0.81: \(\frac{1.017}{0.81} = 1.25679\).

Now, since \(1.25679 = x + 1\), solve for \(x\):

- Subtract 1 from both sides: \(x = 1.25679 - 1 = 0.25679\).

Let's look at the options:

- Option 1: -0.8

- Option 2: 0.7

- Option 3: 1

- Option 4: -0.5

Option 2: 0.7 is the closest to the calculated value.
