A national chain of consumer electronics stores had the business objective of determining the effectiveness of newspaper advertising. To promote sales, the chain relies heavily on local newspaper advertising to support its modest exposure in nationwide television commercials. A sample of 20 cities with similar populations and monthly sales totals were assigned different newspaper advertising budgets for one month. The data is used to predict the sales (in $millions) using the newspaper advertising budgets (in $thousands) observed during the study. The first few lines of data are given below:
Sales ($milions) Newspaper Advertising ($thousands)
6.14 5
6.04 5
6.21 5
6.32 5
6.42 10
Required:

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x β 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x β 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x β 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
