Answer:
Hey there!
First, we want to find the side length of the large triangle.
1/2bh=y cm^2

Since b and h are the same here, we have b^2= 2y, 
.
And we have FC=
.
Area of shaded triangle: 
.
This is equal to: 
, or y/4.
Let me know if this helps :)
Answer: 4x=3y, 8x=6y
Step-by-step explanation: We can use a simplified form of an equation for this specific problem, since a solution is (3,4), if you plugin 3 for x and 4 for y you get the same thing. Since 4 times 3 equals 3 times 4 you can call x as 4 and y as 3. You can simply multiply this by 2 for another equation since it doesn't affect the ratio. I hope this helps!
