SOLUTION: ok. 3y=9x+12 i know you divide 3y by 3 to cancel it out so all you have is y. and then i know you divide 12 by 3 to get 4. this makes it y=9x+4. do i also divide 9x by 3

Question 142541: ok.
3y=9x+12

i know you divide 3y by 3 to cancel it out so all you have is y.
and then i know you divide 12 by 3 to get 4.
this makes it y=9x+4.
do i also divide 9x by 3?
then the answer is
y=3x=4.
this looks more right.

3%2Ay=9%2Ax%2B12 Start with the given equation


y=%289%2Ax%2B12%29%2F%283%29 Divide both sides by 3.


y=%289%2Ax%29%2F%283%29%2B%2812%29%2F%283%29 Break up the fraction

y=3x%2B4 Reduce 9x%2F3 to get 3x. Reduce 12%2F3 to get 4.


So you are correct
