Question

tìm x :

\(\frac{-3}{7} +x=\frac{1}{3}\)

giúp mk nha mk cần gấp lắm

Answer 1

Ta có:

\(-\frac{3}{7}+x=\frac{1}{3}\)

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

=>\(x=\frac{1}{3}+\frac{3}{7}=\frac{16}{21}\)

Vậy......

Answer 2

-3/7+x=1/3

x=1/3--3/7

x=7/21+9/21

x=16/21

Answer 3

\(\frac{-3}{7}+x=\frac{1}{3}\)

\(x=\frac{1}{3}-\frac{-3}{7}\)

\(x=\frac{16}{21}\)

Answer 4

\(\frac{-3}{7}+x=\frac{1}{3}\)

\(x=\frac{1}{3}-\frac{-3}{7}\)

\(x=\frac{16}{21}\)
