Answer 2

Did the question tell you the solutions to x and y?

Answer 3

nope

Answer 4

How did they get 9x from 7?

Answer 5

idk bruh

Answer 6

9x + 3y = 21

Answer 7

That is the solution.

Answer 8

so my first answer is 21

Answer 9

The blanks in order are 3 and 21.

Answer 10

where did you get 21 from?

Answer 11

yea how

Answer 12

wait is it 9x+3 and y= 21

Answer 13

You can add matching coefficients with every term of a polynomial, as long as they ae proportional.

Answer 14

Basically, 9x = 3(3x), so I multiplied every other term by three to make the two equations coincident.

Answer 15

Do you get it now?

Answer 16

OO thanks

Answer 17

No problem, and by the way, it is 9x + 3y = 21, not 9x+3 and y = 21

Answer 18

Any other problems you have you can tag me in ;)
