Solution 1

The system of equations is:

-2x - 3y = 9 -x = y

Step 1: Solve the second equation for x -x = y Multiply both sides by -1 to get: x = -y

Step 2: Substitute x = -y into the first equation -2(-y) - 3y = 9 2y - 3y = 9 -y = 9 Multiply both sides by -1 to get: y = -9

Step 3: Substitute y = -9 into the Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
