Question

[Trần Đức Minh Quang]

x-8/27 = 7/27

Answer 1

[Lonely Member]

x=7/27+8/27

x=15/27

x=5/9

Answer 2

[Ăn CHơi Éo sỢ mƯa rƠi]

\(x-\frac{8}{27}=\frac{7}{27}\)

\(x\in\left(-\infty;\infty\right)\)

\(\frac{27x-8}{27}=\frac{7}{27}\Rightarrow\left(27x-8\right)27=27.7\)

\(\frac{\left(27x-8\right)27}{27}=\frac{27.7}{27}\)

\(27x-8=\frac{27.7}{27}\)

Rút gọn :

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