Answer 2

To solve the equation -2.4(7-9y) = 3.2, we can follow these steps:

1. Distribute the -2.4 to the terms inside the parentheses: -2.4 * 7 + 2.4 * 9y = 3.2

2. Simplify the equation: -16.8 + 21.6y = 3.2

3. Move the constant term to the other side of the equation: 21.6y = 3.2 + 16.8

4. Combine like terms: 21.6y = 20

5. Divide both sides of the equation by 21.6 to solve for y: y = 20 / 21.6

Now, let's calculate the value of y:

y = 20 / 21.6 = 0.9259259259259259

Therefore, the solution to the equation -2.4(7-9y) = 3.2 is y = 0.9259259259259259.

Please note that the solution has been calculated based on the given equation.
