To solve this let our write this fraction in terms.

/

So now let change this problem as a multiplication problem. To change this to multiplication problem we have to flip our second term

So, now let's simplify the terms. So we get
Thus this is our final answer.
Step-by-step explanation:
Consider the provided equation.
P=2(l+w)P=2(l+w)
We need to solve the equation for I.
Divide both the sides by 2.
{P}{2}=\frac{2(l+w)}{2}2P=22(l+w)
{P}{2}=l+w2P=l+w
Now isolate the variable I.
Subtract w from both side.
\{P}{2}-w=l+w-w2P−w=l+w−w
I{P}{2}-wI=2P−w
The value of the equation for I is I=\frac{P}{2}-wI=2P−w .
Idk but this might help o_o
