Solution 1

Sure, let's solve the system of linear equations first:

  1. x + y = 7
  2. 2x - 3y = 4

Step 1: Solve the first equation for x:

x = 7 - y

Step 2: Substitute x in the second equation:

2(7 - y) - 3y = 4 14 - 2y - 3y = 4 14 - 5y = 4 5y = 14 - 4 5y = 10 y = 10 / 5 y = 2

Step 3: Substitute y = 2 into t Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
