We know there are 4 quarts in a gallon, so how many quarts in 2.5 gallons anyway?
9(2w−y)=21w−9y
First you multiply the numbers in the parenthesis by 9
![18w-9y=21w-9y](https://tex.z-dn.net/?f=18w-9y%3D21w-9y)
subtract. 21w-18w=3w
![-9y=3w-9y](https://tex.z-dn.net/?f=-9y%3D3w-9y)
add. -9y+9y=0
![0=3w](https://tex.z-dn.net/?f=0%3D3w)
divide.
![0=w](https://tex.z-dn.net/?f=0%3Dw)
Final answer is 0.
a = 2x + 6xz
a = x(2 + 6z) <em>factored out "x" on right side</em>
a/(2 + 6z) = x <em>divided both sides by (2 + 6z)</em>
Answer: x = ![\frac{a}{2 + 6z}](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7B2%20%2B%206z%7D%20%20)
the anwser would most likely be 3 because you want the LCM
