-2(3-4x)+5(2-1,6x)=4

To solve the equation \(-2(3 - 4x) + 5(2 - 1.6x) = 4\), follow these steps:

1. Distribute the terms: \[ -2(3) + -2(-4x) + 5(2) + 5(-1.6x) = 4 \] \[ -6 + 8x + 10 - 8x = 4 \]

2. Combine like terms: \[ (-6 + 10) + (8x - 8x) = 4 \] \[ 4 + 0 = 4 \]

3. This simplifies to: \[ 4 = 4 \]

Since this statement is always true, it indicates that the equation is true for all values of \(x\). Thus, the solution set is:

All real numbers.
