Let's solve this complex number addition problem step by step. We need to add (7 + 3i) and (-8 + 9i). In the complex plane, we can visualize these numbers as points or vectors. The blue vector represents 7 + 3i, and the red vector represents -8 + 9i. To add complex numbers, we add the real parts together and the imaginary parts together.
