Answer 2

To solve the equation 0.4(8 - 4y) = 3.2 - 0.8(y - 7), you can follow these steps:

1. Distribute the values on the left and right sides of the equation:

0.4 * 8 - 0.4 * 4y = 3.2 - 0.8 * y + 0.8 * 7

2. Simplify each term:

3.2 - 1.6y = 3.2 - 0.8y + 5.6

3. Now, combine like terms on each side of the equation:

-1.6y = -0.8y + 5.6

4. To isolate the variable 'y' on one side of the equation, you can add 0.8y to both sides:

-1.6y + 0.8y = 5.6

-0.8y = 5.6

5. Finally, divide both sides by -0.8 to solve for 'y':

y = 5.6 / -0.8

y = -7

So, the solution to the equation is y = -7.
