Complete the standard form of the equation -4y=3-2y.

-4y = 3 - 2y
+2y = +2y

-2y = 3
---
-2 -2

Y= -1.5

So your goal is to get x all alone
To achieve this you would have to add 2y to both sides to become -2y = 3
Then you would have to divide both sides by -2 (so y is all alone)
When you divide it it comes out to be y = -1.5

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's
