If you're that paranoid, set your computer volume to 0 before looking? :(

Seriously, unless two step equations are classified as "scary links" then their legit.

OpenStudy (anonymous):
Ah okay, well can you point me in the right direction?

\[ \frac{1}{3}x=12\]
If you just want \(x\) by itself, you can multiply both sides by 3, since \(\frac{1}{3}\cdot 3= \frac{3}{3}=1\)
OpenStudy (anonymous):
Is 1 the answer? If so, there is no answer choice for that.
OpenStudy (kirbykirby):
No. If you multiply both sides by 3, what you get is:
\[ \frac{1}{3}x\cdot 3=12 \cdot 3\]
OpenStudy (kirbykirby):
Which implies \(x = 12 \cdot 3\)

yeah
OpenStudy (anonymous):
Alright, and is my last one correct or also wrong?
OpenStudy (kirbykirby):
Wrong :s
What you have is \(3x+3=21\)
Subtract 3 from both sides: \(3x + 3 - 3 = 21 - 3\)
OpenStudy (anonymous):
18.
OpenStudy (kirbykirby):
\(3x = 18\)
To isolate x now, divide both sides by 3
