Answer 2

To solve the equation -4(3 - 4x) + 10(2 - 1.6x) = 8, follow these steps:

1. Distribute the constants inside the parentheses: -4(3) + 4(4x) + 10(2) - 10(1.6x) = 8

2. Perform the multiplications inside the parentheses: -12 + 16x + 20 - 16x = 8

3. Combine like terms: (-12 + 20) + (16x - 16x) = 8

4. Simplify: 8 + 0 = 8

So, the equation simplifies to:

8 = 8

This is an identity, meaning the equation is true for all values of x. In other words, there is no specific solution for x because the original equation is always true.
