Question

Can someone please help me!!!

Choose the correct option that explains what steps were followed to obtain the system of equations below.

Answer 1

The correct answer is the first one(a): To get the system B,..., the first equation multiplied by 4...

Step-by-step 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
