How do I do this?? Help!

Hi there!
In order to use the elimination method, you have to create one variable that has the same coefficient. This is to be able to eliminate one variable and have a one variable equation (which you can then solve).
In your case, we'll have the "x" have the same coefficient by multiplying the top equation by 4 and the bottom equation by 2 :
4( -2x + 3y = -4) → -8x + 12y = -16
2( 4x - 2y = 16) → 8x - 4y = 32
Now that both of your equation have a variable with the same coefficient, you need to choose rather you need to add or subtract the equations in order to get rid of the variable (in this case we want to get rid of the "x").
In your case, you want to add both equation together which will give you :
8y = 16
Now that you only have one variable, all you need to do now is solve the equation for "y" :
8y = 16
Divide each side of the equation by 8
y = 2 → Your answer
There you go! I really hope this helped, if there's anything just let me know! :)

a. If three-tenths of the visitors were adults and there were 100 visitors, how many visitors were adults?
b. Five-eighths of the prizes at the Giant Spin were dolls. If there were 64 prizes, how many prizes were NOT dolls?
Answers
Answer: a) 30 and b) 24.
Step-by-step explanation:
Since we have given that
a) Number of visitors = 100
According to question, we get that If three-tenths of the visitors were adults.
So, number of adults would be
b) Number of prizes = 64
According to question, Five-eighths of the prizes at the Giant Spin were dolls.
So, Number of prizes are not dolls is given by
Hence, a) 30 and b) 24.
B. 5/8 x64/1 =40 dolls
therefore 64-40=24 were not dolls

Let's imagine that the shortest size is 1
So as it is half of the second the second must be2
As it is the third of the longest size it must be 3
To find the perimeter we must add the three sides.
1+2+3=6
Therefore the perimeter is the double of the longest size
or
The longest size is half of the perimeter
We must take one or two more examples to be sure...
I will take another one
Let's imagine that the shortest size is 5
So as it is half of the second the second must be10
As it is the third of the longest size it must be 15
To find the perimeter we must add the three sides.
5+10+15=30
Therefore the perimeter is the double of the longest size
or
The longest size is half of the perimeter
