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

In order to combine like terms, let's rearrange the variables in the following order: x, y, and c.

The expression becomes:

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

Combining like terms, we have:

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

This simplifies to:

9x + 7y - 5c - 9

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

First, let's group the like terms together:

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

Next, let's simplify each group individually:

9x: This is already simplified.

3y + 4y: Combining these like terms, we get 7y.

-6 - 3 - 5c: Combining these terms, we get -9 - 5c.

Putting it all together, the simplified expression is:

9x + 7y - 9 - 5c

To simplify the given expression: 9x + 3y - 6 - 5c + 4y - 3, combine like terms by grouping the similar variables together.

First, let's group the x term:
9x

Next, let's group the y terms:
3y + 4y = 7y

Now, let's group the constant terms:
-6 - 3 = -9

Finally, the expression simplifies to:
9x + 7y - 5c - 9
