Answer:-5738

Step-by-step explanation:One positive number “

” is 6 more than twice another “y“xEquation 1: y = 2x + 8

Their product is 731, therefore…

Equation 2: x * y = 731

SubstituteNew Equation: x(2x + 8) = 731

Solvex (2x + 8) = 731 Perform the multiplication by distributing the x

+ 8x = 731 Divide entire equation by 2, the coefficient of x2

+ 4x = 365.5 Set equation (it is a quadratic) to 0 in order to solve by subtracting 365.5 from both sides

+ 4x – 365.5 = 0 We can solve this using the Quadratic Formula or by Factoring.
