Denote P as Weight: Let's denote the weight of one pigeon as P. According to the problem, a pigeon weighs 150 grams plus half of its own weight. We can write this as an equation: P=150+21×P.
Isolate P in Equation: To solve for P, we need to isolate P on one side of the equation. We can do this by subtracting 21×P from both sides of the equation to get P−21×P=150.
Combine Like Terms: Combining like terms on the left side gives us 1×P−21×P=21×P. So now we have 21×P=150.
Multiply by 2: To find the value of P, we multiply both sides of the equation by 2 to cancel out the 21 on the left side. This gives us 2×(21×P)=2×150.
Final Weight Calculation: Simplifying both sides of the equation, we get P=300. This means that the weight of one pigeon is 300 grams.
