9.) <span>1/2(4x-6)=11
</span>Multiply 4 and -6 by 1/2
2x-3=11
Add 3 to both sides
2x=14
Divide 14 by 2
Final Answer: x=7
10.) 2/3(6x-9)=-34
Multiply 6 and -9 by 2/3
4x-6=-34
Add 6 to both sides
4x=-34
Divide -34 by 4
Final Answer: x=-8.5

We now cross multiply or use the butterfly method which I will demonstrate both
<h3>Cross Multiply</h3>
We multiply the numerator with the dominator
so 
and 



or 
Now for the
<h3>Butterfly Method </h3>
You would do 7 times 24 divided by 60 or 
Then
simplify
so 2.8 miles in either method
