Question

Tìm x:

2x+x=54:7

Answer 1

\(2x+x=54:7\)

\(3x=\frac{54}{7}\)

\(x=\frac{54}{7}:3\)

\(x=\frac{54}{7.3}\)

\(x=\frac{18}{7}\)

Vậy \(x=\frac{18}{7}\)

Answer 2

\(2x+x=\frac{54}{7}\)

\(3x=\frac{54}{7}\)

\(x=\frac{54}{7}:3\)

\(x=\frac{18}{7}\)

Answer 3

\(\left(2+1\right)\)*x=\(\frac{54}{7}\)

3x=\(\frac{54}{7}\)

x=\(\frac{54}{7}\):3

x=\(\frac{18}{7}\)
