9x + 3y = 21
That is the solution.
so my first answer is 21
The blanks in order are 3 and 21.
where did you get 21 from?

yea how
wait is it 9x+3 and y= 21
You can add matching coefficients with every term of a polynomial, as long as they ae proportional.
Basically, 9x = 3(3x), so I multiplied every other term by three to make the two equations coincident.
Do you get it now?

OO thanks
No problem, and by the way, it is 9x + 3y = 21, not 9x+3 and y = 21
Any other problems you have you can tag me in ;)
