Question below!!

Choose the equivalent system of linear equations that will produce the same solution as the one given below.

4x - y = -11
2x + 3y = 5

-4x - 9y = -19
-10y = -30

4x + 3y = 5
2y = -6

7x - 3y = -11
9x = -6

12x - 3y = -33
14x = -28

Answer 1

I would suggest first solving the system of equations
4x - y = -11
2x + 3y = 5
for x and y...

Answer 2

here is what I did (I used substitution method)
4x - y = -11 --> y = 4x + 11
2x + 3y = 5
= 2x + 3(4x + 11) = 5 distribute
2x + 12x + 33 = 5 add like terms and subtract both sides by 33
14x = -28
