Inventory Audit Cost Reconciliation

As an office manager auditing your department's supply orders, you need to find the unit prices of Premium Binders (xx) and Standard Organizers (yy). Your purchase history is modeled by the following system of linear equations:

3x4y=9{}3x - 4y = -9 5x+3y=14{}5x + 3y = 14

To solve this system using the elimination method to determine the unit prices, you decide to eliminate the Standard Organizers (yy) first. Recall the standard algebraic procedure for elimination to answer the following questions:

  1. By what positive integer constants must you multiply the first and second equations respectively to make the coefficients of yy opposites?
  2. What are the resulting opposite coefficients of yy after these multiplications?
