This gives:
---- This represents (A)
Open bracket
---- This represents (B)
In algebra:
means 
So, the expression becomes
--- This represents (D)
<em>This implies that (C) does not represent the perimeter</em>
1 Let's solve for x.
y = 5x -7x
Step 1: Flip the equation.
-2x = y
Step 2: Divide both sides by -2
-2x/-2 = y/-2
X= -1/2 y
Answer
X= -1/2 y
