Question

Chỉ mk vs, mình cần gấp, ai nhanh mik tick cho:

2x+1/3x+5=3/7

Answer 1

Ta có :

2x + \(\frac{1}{3}\)x + 5 = \(\frac{3}{7}\)

x . (2 + \(\frac{1}{3}\)) = \(\frac{3}{7}\)- 5

x . \(\frac{7}{3}\)= \(\frac{-32}{7}\)

x  = \(\frac{-32}{7}\)\(:\)\(\frac{7}{3}\)\(=\)\(\frac{-96}{49}\)

Answer 2

6/3x +1/3x +5 -3/7= 0

7x +35/7 -3/7= 0

7x +32= 0

x= -4.57 ( xấp xỉ)

Answer 3

\(2x+\frac{1}{3}x+5=\frac{3}{7}\)

\(x×\left(2+\frac{1}{3}\right)=\frac{3}{7}-5\)

\(x×\left(2+\frac{1}{3}\right)=\frac{-32}{7}\)

\(x×\frac{7}{3}=\frac{-32}{7}\)

\(x\)        \(=\frac{-32}{7}:\frac{7}{3}\)

\(x\)       \(=\frac{-96}{49}\)
