Question

In solving {2x + 7y = −24x + 3y = −10 by using elimination, you could eliminate the x variable in one step by multiplying the first equation by

A-2. This would change it to -4x - 14y = 4
B-2. This would change it to -4x - 14y = 2
C4. This would change it to 8x + 28y = -8
D-1. This would change it to -2x - 7y = 2
4. This would change it to 8x + 28y = -8

Answer 1

The answer is "A. -2. This would change it to -4x - 14y = 4"
