Question

Tìm x, biết

a) \(2\frac{2}{3}.x+8\frac{2}{3}=3\frac{1}{3}\)

Answer 1

8/3.x+26/3=10/3

8/3.x= 10/3-26/3

8/3.x = -5/1/3

x= -5/1/3 :8/3

x=-2

Answer 2

\(2\frac{2}{3}.x+8\frac{2}{3}=3\frac{1}{3}\)

\(\frac{8}{3}.x+\frac{26}{3}=\frac{10}{3}\)

\(\frac{8}{3}.x=\frac{10}{3}-\frac{26}{3}=-\frac{16}{3}\)

\(x=-\frac{16}{3}:\frac{8}{3}=-2\)

Answer 3

8/3.x+26/3=10/3

8/3.x= 10/3-26/3

8/3.x = -5/1/3

x= -5/1/3 :8/3

x=-2

Answer 4

\(2\frac{2}{3}.x+8\frac{2}{3}=3\frac{1}{3}\)\(=>\frac{8}{3}.x+\frac{26}{3}=\frac{10}{3}\)

\(=>\frac{8}{3}.x=\frac{10}{3}-\frac{26}{3}=>\frac{8}{3}.x=\frac{-16}{3}\)

\(=>x=\frac{-16}{3}:\frac{8}{3}=>x=\frac{-48}{24}=-2\)
