Question

Select the best possible first step to solving the system by first eliminating the x variable.

3x + 5y = 1
2x + 4y = -4

A) Multiply the first equation by 2, and multiply the second equation by 3.

B) Multiply the first equation by -2, and multiply the second equation by 3.

C) Multiply the first equation by -2, and multiply the second equation by -3.

D) None of the above

Answer 1

The second one, because you want to cancel one of the variables, the second one cancels out the x variable if you carry through.

Answer 2
