One positive integer is 3 less than twice another. The sum of their squares is 954. Find the integers

x = integer

 

x    =   2y -3

 

x + y = 954        

(2y-3) 2   +   y 2 = 954    

4y^2 -12y+9 + y^2 - 954 = 0

5 y^2 -12y - 945 = 0

Then use Quadratic Formula   a = 5  b = -12  c = -945

 

y = 15                     then x = 2y-3 = 27                   *** edited ****    Thanx, Guest !
