Answer: To get system B, the second equation in system A was replaced by the sum of that equation and the first equation multiplied by 5. The solution to system B will be the same as the solution to system A.
Step-by-step explanation:
The correct answer is the first one(a): To get the system B,..., the first equation multiplied by 4... Explanation: 1. Let us first multiple the first equation in System A with 4, we would get: 4(2x - y) = 4 * 3 => 8x - 4y = 12 --- (A) Now add the equation (A) and the second equation of System A: 8x - 4y = 12 3x + 4y = 10 ------------------11x = 22 Hence, System B: 2x - y = 3 11x = 22 -i
