To eliminate the terms and solve for y in the fewest steps, by which constants should the equations be multiplied by before adding the equations together? First equation: 9x + 3y = -18

Second equation: 8x + 7y = 10

A)The first equation should be multiplied by 3 and the second equation by 7.
B)The first equation should be multiplied by -3 and the second equation by -7.
C)The first equation should be multiplied by - 7 and the second equation by 3 .
D)The first equation should be multiplied by -7 and the second equation by -3.

the answer is a

step-by-step explanation:

because your just changing the position of where the shape is

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.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
