Question

Beatrice wanted to solve the system of equations { 4x − 3y = 9 3x + 2y = 11 by elimination. To eliminate the x-terms, Beatrice could multiply the first equation by and the second equation by and add equations. −4 3 3 2 A

Answer 1

Explanation:

The system of linear equations that Beatrice wanted to solve by the method of elimination is expressed as

4x − 3y = 9 - - - - - - - - -1

3x + 2y = 11 - - - - - - - - - - 2

In order to eliminate the x- terms, Beatrice could multiply the first equation by 3 and the second equation by - 4 and add the first equation to the second equation. This would make the x terms to be equal. The x terms in the first and second equations becomes 12x and - 12x
