2(2,5x -1)=-(1,8-4x)

Let's solve the equation step by step.

Given: \[ 2(2.5x - 1) = -(1.8 - 4x) \]

1. Distribute the 2 on the left side: \[ 2 \cdot 2.5x - 2 \cdot 1 = 5x - 2 \]

   So the left side becomes: \[ 5x - 2 \]

2. Distribute the negative sign on the right side: \[ -(1.8) + 4x = -1.8 + 4x \]

   So the right side becomes: \[ -1.8 + 4x \]

Now rewrite the equation: \[ 5x - 2 = -1.8 + 4x \]

3. Get all terms involving \(x\) on one side and constant terms on the other: \[ 5x - 4x = -1.8 + 2 \] \[ x = 0.2 \]

So the solution to the equation is: \[ x = 0.2 \]
