Can you explain
OpenStudy (anonymous):
Yes
add 2q to both sides.
subtract 5 to both sides.
5q = 15
divide 5 to both sides.
the answer is: q = 3

keep this rule in mind @TheAsker2002
whatever you do the left side of an equation, do same to the right side.
you need all the q's on one side, and everything else on the other side
to move -2q to the left side, you do -2q+2q which will give you 0
and then since the only thing you did to the right side was +2q, you do same to the left side
so 3q+2q
now you have 5q
use the same principle for the 5, and the rest is easy.
just a longer explanation of what @Kyliejones did
