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

bixtya [17]

Answer:

C

Step-by-step explanation:

Given

30( \frac{1}{2} x - 2) + 40( \frac{3}{4} y - 4)

Multiply each of the terms in the first parenthesis by 30 and multiply each of the terms in the second parenthesis by 40.

= 15x - 60 + 30y - 160

= 15x + 30y - 220 → C
