Question

Sa se rezolve ecuatia: x+3/3 + x+7/5 + x+11/7 + x+19/11 + x+23/13 = 10
                                

Answer 1

x+3/3 amplificat cu 5x7x11x13, +x+7/5 amplificat cu 3x7x11x13, +x+11/7amplificat cu 3x5x11x13 , + x+19/11 amplificat cu 3x5x7x13, + x+23/13 amplificat cu  3x5x7x11=10 amplificat cu 3x5x7x11x13
 =>5005x+15015+3003x+21021+2145x+23595+1365x+25935+1155x+26565=150150
12673x=38064
x=3
