Given:product of 2 numbers is 450.first number is half the second number.Let us make our own equation based on the given data.Let x and y be the two numbers.y * x = 450y is the 1st number. It is said that it is half the second number, x.y = 1/2 * x = x/2Let us substitute y of the 1st equationÂ by its value in the second equation.x/2 * x = 450xÂ² / 2 = 450xÂ² = 450 * 2xÂ² = 900âˆšxÂ² =Â âˆš900x = 30The value of x, the 2nd number, is 30.Â y = x/2 = 30/2 = 15The value of y, the 1st number, is 15.To check:y * x = 45015 * 30 = 450450 = 450
