PLEASE HELP ME


Multiply each equation by a constant that would help to eliminate the y terms.

2 x - 5 y = -21. 3 x - 3 y = -18.

What are the resulting equations?

A) 6 x - 15 y = -63. -15 x + 15 y = 90.

B) 6 x -15 y = 63. -15 x + 15 y = 90.

C) 6 x - 15 y = -63. -15 x + 15 y = -90.

D) 6 x - 15 y = -63. -15 x + 15 y = 90.
