Question

X -  2 =  6

27  9     18

giúp mik giải vs nha

Answer 1

\(\frac{x}{27}-\frac{2}{9}=\frac{6}{18}\)

\(\frac{x}{27}=\frac{6}{18}+\frac{2}{9}\)

\(\frac{x}{27}=\frac{6}{18}+\frac{4}{18}\)

\(\frac{x}{27}=\frac{5}{9}\)

\(\Rightarrow\text{ }9x=27\cdot5\)

\(9x=135\)

\(x=135\text{ : }9\)

\(x=15\)
