3,7х + 2,5у +1,6х + 4,8у

To solve the expression 3.7x + 2.5y + 1.6x + 4.8y, we need to combine like terms.

2.5y and 4.8y are like terms, so they can be added together:

2.5y + 4.8y = 7.3y

Similarly, 3.7x and 1.6x are like terms, so they can be added together:

3.7x + 1.6x = 5.3x

Now, we have:

5.3x + 7.3y

This is the simplified expression.
