We start with the expression:
$$
(5x + 9y) + (-6x + 7y)
$$

**Step 1: Group like terms**

Group the $$ x $$ terms and the $$ y $$ terms separately:
$$
5x + (-6x) \quad \text{and} \quad 9y + 7y
$$

**Step 2: Combine like terms**

For the $$ x $$ terms:
$$
5x - 6x = -x
$$
For the $$ y $$ terms:
$$
9y + 7y = 16y
$$

**Step 3: Write the simplified expression**

The simplified expression is:
$$
-x + 16y
$$
$$-x + 16y$$

Add. \( (5 x+9 y)+(-6 x+7 y) \) The answer is (Simplify your answer.)
