I need help knowing what the difference is : Select the best possible first step to solving the following system by first eliminating the y variable. 5x-3y=1 7x-4y=2 My options are to: Multiply the first equation by 3 and multiply the second equation by 4. Multiply the first equation by -3 and multiply the second equation by -4. Multiply the first equation by -7 and multiply the second equation by 5. None of the above. My instinct is to multiply the equations by either 3 and 4 or -3 and -4, but I don't know what the difference is in multiplying by a negative or a positive.
