Step-by-step explanation:
Given:
The perimeter of a rectangle is given as,

We are asked to express this in terms of
.
Add -2l both sides and simplify. This gives,

Now, we divide both sides by 2 to get an expression in terms of
. This gives,

The answer to your problem is:

Answer:
It has more than one equal sign but set up like this:
Step-by-step explanation:
Let's solve for x.
y+x−1+
3
2
=−y
Step 1: Add -y to both sides.
x+y+
1
2
+−y=−y+−y
x+

2
=−2y
Step 2: Add (-1)/2 to both sides.
x+
