Question

Which of the following systems is equivalent to the given system?

2/3 x - y = 2 x + 1/2y = -3
a) 2x - 3y = 6 and 2x + y = 6
b)6x - 3y = 6 and 2x + y = 10
c) 2x - 3y = 6 and 2x + y = -6

Answer 1

The correct answer is c.

Explanation:

This is because it is the first equation being multiplied by 3 and the second being multiplied by 2.

None of the other examples are multiples of the originals.
