Question

Which system of equations has the same solution as the system below

Answer 1

None of the above.

Explanation:

The system of equations which should have the same solution as the system below;

x + 4y = 11

4x + 2y = 16

is

x + 4y = 11

-8x - 4y = - 32

This system of equations is missing from your choices.

The trick is that -2 is multiplied to the second equation of the first system.

i.e -2 (4x + 2y = 16) gives; -8x - 4y = -32
