a x 3 = b x 2 => a = [tex]\frac{b X 2 }{3}[/tex]
a + b = 50
[tex]\frac{b X 2 }{3}[/tex] + b = 50=> [tex]\frac{3b}{3}[/tex]+[tex]\frac{b X 2 }{3}[/tex] = [tex]\frac{5b}{3}[/tex] = 50
5b = 150
b = 30
a = [tex]\frac{30X2}{3}[/tex] = [tex]\frac{60}{3}[/tex] = 20
Proba : 20 x 3 = 30 x 2 => 60=60
Succes !
