Hello and Welcome to Openstudy! :)

could you try revising your question?
there might have been a typo :)
I see:  -6x +3y = 12y

anonymous · Answer

-3x+6y=12
sorry:(

jigglypuff314 · Answer

much better :)
now tell me, what is the Greatest Common Factor 
of 3, 6, and 12?

anonymous · Answer

3

anonymous · Answer

i think

jigglypuff314 · Answer

yep :)
so you can divide all the values by 3.
-3x divided by 3 = -x
6y divided by 3 = 2y
12 divided by 3 = 4

Use substitution to determine which of the following points is a solution to the standard form equation below.

A. (10,5/2)

B. (5,2/5)

C. (5/2,-5/2)

D. (5/2,-2/5)

can you help me with one more please?

jigglypuff314 · Answer

sure :)
what's the given equation that they want you to use?

the way you would do it would be to plug in the coordinate pairs as (x, y)
so for point (10, 5/2)   you would plug in 10 for x  and   5/2 for y
then simplify and if the two sides equal each other then it works :)

anonymous · Answer

2y=5 is the equation

jigglypuff314 · Answer

could you check again? perhaps you made a typo :)

anonymous · Answer

uumm it says 2y=5 unless the paper is wrong :o

jigglypuff314 · Answer

weird...
I suppose it would still work ;)
could you solve for y given  2y = 5 ?
just divide both sides by 2

anonymous · Answer

ok it worked thank you so much :)
