WebSep 16, 2024 · A real number only carries one piece of information: its location on the number line. So when you add two complex numbers, you need to keep track of the real parts and the imaginary parts separately. In your case, a + b = 4 and − 2 a − 3 b = − 6. So a = 6 and b = − 2. In most cases, it's actually better to think of complex numbers as ...

WebI'll get you started. Take the 2nd equation and add 3x to both sides to isolate "y". y = 3x+3 Now, substitute this value of "y" into the first equation. 3(3x+6) + 2x = 7 You can now solve for "x". Once you have the value of "x", use it to calculate the value of "y". Hope this helps.
