I need help :( please help. Best answer = Brainiest,

Answer:
5
Step-by-step explanation:
let a be the other number
so one number is [tex]\frac{2}{3}a - 3[/tex]
a + [tex]\frac{2}{3}a - 3[/tex] = 17
[tex]\frac{5}{3}a - 3 = 17[/tex]
[tex]\frac{5}{3}a[/tex] = 17 + 3 = 20
a = 20 x [tex]\frac{3}{5}[/tex] = 12
[tex]\frac{2}{3}(12) - 3[/tex] = 5
