Answer 2

Let's solve the given equation step by step:

1. Start with the expression (x÷(-2) + 4.5) ÷ (-1.5) = 3.

2. Simplify the expression inside the first set of parentheses by performing the division first: x ÷ (-2) = -0.5x.

3. Substitute the simplified expression back into the equation: (-0.5x + 4.5) ÷ (-1.5) = 3.

4. Multiply both sides of the equation by -1.5 to eliminate the division on the left side: -1.5 × (-0.5x + 4.5) ÷ (-1.5) = 3 × (-1.5).

5. Simplify the left side of the equation: -1.5 × (-0.5x + 4.5) ÷ (-1.5) = 3 × (-1.5) becomes -0.5x + 4.5 = -4.5.

6. Subtract 4.5 from both sides of the equation: -0.5x + 4.5 - 4.5 = -4.5 - 4.5.

7. Simplify both sides of the equation: -0.5x = -9.

8. Divide both sides of the equation by -0.5 to solve for x: (-0.5x) / -0.5 = -9 / -0.5.

9. Simplify the equation: x = 18.

Therefore, the value of x that satisfies the equation is x = 18.
