(3x+10)2018 + /2y-27/2019=0 (1)
Ta có: ( 3x+10)2018\(\ge\)0, với mọi x
/2y-27/2019\(\ge\)0, với mọi y
(3x+10)2018 + /2y-27/2019=0 (2)
Từ (1) và (2):
\(\Rightarrow\) ( 3x+10)2018 = 0
/2y-27/2019 = 0
\(\Rightarrow\) 3x +10 =0
2y -27 =0
\(\Rightarrow\) 3x+10 = 0
3x = 0-10
3x = -10
x = -10:3
x = \(\dfrac{-10}{3}\)
2x -27 = 0
2x = 0+27
2x = 27
x = 27: 2
x = \(\dfrac{27}{2}\)
Vậy x = \(\dfrac{-10}{3}\); y = \(\dfrac{27}{2}\)
