Do distributive property first!
OpenStudy (shadowlegendx.):
Hmm wait it is divided by 3
OpenStudy (shadowlegendx.):
Multiply both sides by 3 than do distributive property c;

we are stuck can't honestly figure it out.
OpenStudy (shadowlegendx.):
"We" ? :P

my friend and I
OpenStudy (shadowlegendx.):
\[\frac{ -4(a-3) }{ 3 } = 4\]
Multiply both sides by 3
We get
\[-4(a-3) = 12 \]
Then we do distributive property to get
\[-4a - 12 = 12\]
Now we add both sides by 12 to get
\[-4a = 24\]
Now divide both sides by -4 to isolate the variable and keep it positive
We get
\[a = -6\]
OpenStudy (shadowlegendx.):
To check the answer, put -6 in for a :)

No problem :)

okay here is anohter -
3(a+7)/2 = 21
Yes I'm stuck. Tried this one the way you showed above - which made total sense, but can't figure this one out.
