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
