what is x over 3 +7=13

OpenStudy (anonymous):

\[\frac{x}{3}+7=13\]

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

start by isolating the x term. How can you get the x over 3 by itself?

OpenStudy (anonymous):

times both sides by 3 over 1

OpenStudy (anonymous):

no. you need to clear the 7 first.

OpenStudy (anonymous):

oh yeah

OpenStudy (anonymous):

got it. thanks

OpenStudy (anonymous):

in general you will want to get the x term by itself. Which means any terms (like the 7 in this case) that don't have an x need to go to the other side of the equal sign.
