Question

[Đồng Thị Ánh Tuyết]

a)\(\frac{x-12}{4}=\frac{1}{2}\)

b)\(\frac{-2}{3}-\frac{1}{3}x\left(2x-5\right)=\frac{3}{2}\)

c) \(\frac{2}{3}x+\frac{1}{3}\left(x-1\right)=0\)

Answer 1

[‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍...]

\(\frac{x-12}{4}=\frac{1}{2}\)

\(\frac{x-12}{4}=\frac{2}{4}\)

=>x-12=2

=>x=14

Answer 2

[๖ACE✪ʟê❖тʀí❖тιêɴ︵²⁰⁰7 (TMS)★]

\(\frac{x-12}{4}=\frac{1}{2}\)

\(\Leftrightarrow\frac{x-12}{4}=\frac{2}{4}\)

\(\Leftrightarrow x-12=2\)

\(\Leftrightarrow x=2+12\)

\(\Leftrightarrow x=14\)
