You have to prove your work. It can be difficult... But I believe in you! The way to do it, is to do the math out. If you have 2 different exponents, then you'll have to create multiple equations to solve, and use them to find what Y or X is.
Example:
4y + 8<em>x = </em>112
Lets do y first. In order to do this, you need to get Y alone.
4y = 112 - 8x
Then, we divide.
y = 28 - 2x
Then insert your y value into the equation: 4(28 - 2x) + 8x = 112
Solve that, and you will have your x value! Then plug in your x value to find the y value. After that, insert both to check your work. There you go! That's the answer to finding the x. Then plug in your new x value, and complete the equation! Make sure to show all of your work!

Answer: C) 6 units</h3>
==========================================================
Explanation:
Let's find the area of the hexagon. It's composed of two identical (aka congruent) trapezoids.
Each trapezoid has two parallel bases of 4+4 = 8 and 5 units. The height is 3. The area of one trapezoid is
area = height(base1+base2)/2
area = 3*(8+5)/2
area = 19.5
which doubles to 2*19.5 = 39 to represent the area of the entire hexagon
--------------------------------
The volume of any prism is found through this formula
volume = (area of base)*(height of prism)
We just found the area of the base to be 39. The height is unknown, so we'll call it h. The volume is given to be 234.
We end up with this equation
234 = 39h
which solves to h = 6 after dividing both sides by 39. This prism has a height of 6 units.
5y=95
y=95/5(vertically opppsite angles)
5x=85
x=85/ 5(vertically opppsite angles)
