Question

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

3 + 2y = -13
2x + 6y = -32
Submit Answer
- 9x – 6y = 39
2x + 6y = -32
-93 + 2y = 39
2x + 6y = -32
3x – 6y = 39
2x + 6y = -32
-93 - 6y = -13
2x + 6y = -32

Answer 1

Explanation:

simply the first one.

-9x -6y = 39 is nothing else than

3x + 2x = -13 multiplied by -3

which leaves the values and solutions unchanged, as we could simply divide by -3 again and end up with the original system and its solution.
