Answer 2

To solve the equation -0.8(x - 2.5) = -6.4, follow these steps:

Step 1: Distribute the -0.8 on the left side of the equation: -0.8(x) + 0.8(2.5) = -6.4

Step 2: Simplify the right side: -0.8x + 2 = -6.4

Step 3: Subtract 2 from both sides to isolate the term with x: -0.8x = -8.4

Step 4: Divide both sides by -0.8 to solve for x: x = -8.4 / -0.8 x = 10.5

So, the solution to the equation is x = 10.5.
