Question

1,1+0,9y-1,2-1,3x-3,8y

Answer 1

$1.1 + 0.9y - 1.2 - 1.3x - 3.8y = - 0.1 - 2.9y - 1.3x$

Answer 2

It seems like you want to simplify the expression:

1 + 0.9y - 1.2 - 1.3x - 3.8y

To simplify this expression, you can combine like terms. First, group the terms with 'y' and the constants together:

(0.9y - 3.8y) + (1 - 1.2 - 1.3x)

Now, simplify each group:

(-2.9y) + (-0.2 - 1.3x)

Finally, combine the two groups:

-2.9y - 0.2 - 1.3x

So, the simplified expression is:

-2.9y - 0.2 - 1.3x
