How long is the trail on your table then multiply by 6.
Just plug in 4 for the x
2*4 +4y =36
8+4y =36
4y =36-8
4y=28
y= 28/4
y=7
Answer: 
Step-by-step explanation:
To solve for y, we want to isolate y.
[multiply both sides by y]
[subtract both sides by 3y]
[factor out y]
[divide both sides by (w-3)]

Now, we know that
.
Green is 4 and Purple is 6 so you put it in a fraction by adding all of them and the just green and purple so 10/30 simplified is 1/3.
