Question

im having trouble with this one too.

6y-8=-6+3y+13

heres what ive done so far...not good.

6y-8=-6+3y+13
6y-8=7+3y
-6y -6y
8=7-3y

Answer 1

Ok I think this is how it goes:
6y-8=-6+3y+13
First add 8 to both sides
6y=15+3y
Next subtract your 3y from both sides
3y=15
so y must = 5
3(5)= 15
I think this is right

Answer 2

do you combine like terms before you add the 8 to both sides?

Answer 3

The order of operations will not affect the answer, but it is best to "clean up" the equation first by combining terms, so the next step to perform will be easier to figure out.
