simplify 9x plus 3y - 6 - 5x plus 4y - 3.

To simplify the expression 9x + 3y - 6 - 5x + 4y - 3, we can simplify like terms.

Combining the x terms, we have:
9x - 5x = 4x

Combining the y terms, we have:
3y + 4y = 7y

Combining the constant terms, we have:
-6 - 3 = -9

Therefore, the simplified expression is:
4x + 7y - 9.

To simplify the expression 9x + 3y - 6 - 5x + 4y - 3, you can combine like terms.

Combining like terms means adding or subtracting coefficients with the same variable.

Let's simplify it step by step:

First, combine the x terms:
9x - 5x = 4x

Then, combine the y terms:
3y + 4y = 7y

Next, combine the constant terms:
-6 - 3 = -9

Putting it all together, the simplified expression is:
4x + 7y - 9

To simplify the expression 9x + 3y - 6 - 5x + 4y - 3, we can combine the like terms.

First, let's group the x terms together:

9x - 5x + 3y + 4y - 6 - 3

Next, combine the like terms.

(9x - 5x) + (3y + 4y) + (-6 - 3)

Simplifying further:

4x + 7y - 9

Therefore, the simplified expression is 4x + 7y - 9.
