-5(1-0,5y)-1,1=0,2(2y+1)

Let's solve the equation step by step:

Given the equation:

\[-5(1 - 0.5y) - 1.1 = 0.2(2y + 1)\]

1. Distribute on both sides:

   Left side: \[-5(1 - 0.5y) = -5 + 2.5y\] Thus, the left side becomes: \[-5 + 2.5y - 1.1 = 2.5y - 6.1\]

   Right side: \[0.2(2y + 1) = 0.4y + 0.2\]

2. Rewrite the equation:

   So now the equation is: \[2.5y - 6.1 = 0.4y + 0.2\]

3. Get all terms involving \(y\) on one side and constant terms on the other side:

   \[2.5y - 0.4y = 0.2 + 6.1\]

   This simplifies to: \[2.1y = 6.3\]

4. Solve for \(y\):

   Now, divide both sides by 2.1: \[y = \frac{6.3}{2.1} = 3\]

So, the solution to the equation is:

\[ \boxed{3} \]
