First, distribute the -0.3 on the terms inside the parentheses:

-(y-0.6) -0.3*(-2y-0.8) = 5
= -y + 0.6 + 0.6y + 0.24 = 5

Now, combine like terms:

-y + 0.6 + 0.6y + 0.24 = 5
= 0.6y - y + 0.84 = 5
= -0.4y + 0.84 = 5

Now, isolate y by subtracting 0.84 from both sides:

-0.4y + 0.84 = 5
-0.4y = 5 - 0.84
-0.4y = 4.16

Finally, divide by -0.4 to solve for y:

y = 4.16 / -0.4
y = -10.4

Therefore, the solution to the equation is y = -10.4.
