Question

Tìm x :

-22/5x +1/3 = [ -2/3 +1/5]

Answer 1

-22/5x + 1/3 = [ - 2/3 + 1/5 ]

-22/5x + 1/3 = 7/15

-22/5x = 7/15 - 1/3

-22/5x = 2/15

5x = (-22) / 2/15

5x = -165

x = -33

 

chúc bạn học tốt ^^

Answer 2

\(-\frac{22}{5x}+\frac{1}{3}=-\frac{2}{3}+\frac{1}{5}\)

=> \(-\frac{22}{5x}+\frac{1}{3}=-\frac{7}{15}\)

=> \(-\frac{22}{5x}=-\frac{7}{15}-\frac{1}{3}\)

=> \(-\frac{22}{5x}=-\frac{4}{5}\)

=> x=27.5

Mừn cx ko chắc. Sợ sai đề :(
