Question

Tìm x, biết: 1/2 - |x-3| : 2 = 1

Answer 1

Answer 2

Ta có: \(\dfrac{1}{2}-\left|x-3\right|:2=1\)

\(\Leftrightarrow\left|x-3\right|:2=\dfrac{1}{2}-1=\dfrac{-1}{2}\)

\(\Leftrightarrow\left|x-3\right|=-1\)(Vô lý)

Answer 3

\(\dfrac{1}{2}-\left|x-3\right|:2=1\)

\(\Rightarrow\left|x-3\right|:2=\dfrac{-1}{2}\)

\(\Rightarrow\left|x-3\right|=-1\) (vô lí)

\(\Rightarrow x=\varnothing\)

Answer 4

\(\dfrac{1}{2}-\left|x-3\right|=2\)

\(\left|x-3\right|=-\dfrac{3}{2}\)

\(\rightarrow\)không tìm được x thỏa mãn
