Answer:
[tex]\frac{P}{2} - x = y[/tex]
Step-by-step explanation:
Given the equation: P = 2(x + y),
Divide both sides by 2 to eliminate the fraction from the right-hand side of the equation:
P = 2(x + y)
[tex]\frac{P}{2} = \frac{2(x + y)}{2}[/tex]
[tex]\frac{P}{2} = x + y[/tex]
Then, subtract x from both sides to solve for y:
[tex]\frac{P}{2} - x = x + y - x[/tex]
[tex]\frac{P}{2} - x = y[/tex]
