0,4(6-4y)-3,5+1,5y+1,9

2,4-1,6у-3,5+1,5у+1,9

0,8-0,1у

Answer 2

To simplify the expression, let's start by distributing the terms within the parentheses:

0.4(6-4y) = 2.4 - 1.6y

Now, let's substitute this back into the original expression:

0,4(6-4y)-3,5+1,5y+1,9 = (2.4 - 1.6y) - 3.5 + 1.5y + 1.9

Next, let's combine like terms:

2.4 - 1.6y - 3.5 + 1.5y + 1.9 = (2.4 - 3.5 + 1.9) + (-1.6y + 1.5y)

Simplifying further:

2.4 - 3.5 + 1.9 = 1.8

And:

-1.6y + 1.5y = -0.1y

Putting it all together:

0.4(6-4y)-3.5+1.5y+1.9 = 1.8 - 0.1y
