Question

Rewrite the equation below in standard form.
-3x+6y=12
A. 3x-6y=12
B. 3x-6y=-12
C. -x+2y=4
D. x-2y=-4

Answer 1

why not b. though?

Answer 2

standard form is Ax + By = C

-3x + 6y = 12 (we do not want x to be negative, so we will multiply the entire equation by -1)
-1(3x + 6y) = -1(12)
3x - 6y = -12 --> standard form

but I think you can divide by 3 and the answer would be : x - 2y = -4

can there be more then one answer ?

Answer 3

I would go with B.

Answer 4

ok
