-15x + 2y - 5 +16x - y + 6

-15x + 2y - 5 + 16x - y + 6 can be simplified further.

Combining like terms, we have:

(-15x + 16x) + (2y - y) + (-5 + 6)

This simplifies to:

x + y + 1

To simplify the expression -15x + 2y - 5 + 16x - y + 6, we need to combine like terms.

First, let's combine the x terms:
-15x + 16x = 1x or x

Next, let's combine the y terms:
2y - y = 1y or y

Finally, let's combine the constant terms:
-5 + 6 = 1

Putting it all together, the simplified expression is:
x + y + 1

To simplify the expression -15x + 2y - 5 + 16x - y + 6, we can combine like terms.

Like terms are terms that have the same variables raised to the same powers. In this expression, the terms -15x and 16x both have the variable x raised to the power 1, and the terms 2y and -y both have the variable y raised to the power 1.

So, let's group the like terms together:

(-15x + 16x) + (2y - y) + (-5 + 6)

Simplifying each of the grouped terms:

(16x - 15x) + (2y - y) + (6 - 5)

Subtracting the coefficients of x:

x + (2y - y) + (6 - 5)

Subtracting the coefficients of y:

x + y + (6 - 5)

Subtracting the constants:

x + y + 1

Thus, the simplified expression is x + y + 1.
