What, if any, is the solution of this system? 4x - 5y= 20
3x - 4y= 12

A. x = 8, y=3

B. x = 10, y = 4

C. x = 15, y = 8

D. x = 20, y= 12

E. It has no solution.​

I *think* it's E.

Step-by-step explanation:

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
