Question

|\(x+\frac{3}{4}\left|-\frac{1}{2}=0\right|\)

Answer 1

\(\left|x+\frac{3}{4}\right|-\frac{1}{2}=0\)

\(=>\left|x+\frac{3}{4}\right|=0+\frac{1}{2}\)

\(=>|x+\frac{3}{4}|=\frac{1}{2}\)

\(=>\left[{}\begin{matrix}x+\frac{3}{4}=\frac{1}{2}\\x+\frac{3}{4}=-\frac{1}{2}\end{matrix}\right.\)

\(=>\left[{}\begin{matrix}x=\frac{1}{2}-\frac{3}{4}\\x=-\frac{1}{2}-\frac{3}{4}\end{matrix}\right.\)

\(=>\left[{}\begin{matrix}x=-\frac{1}{4}\\x=-\frac{5}{4}\end{matrix}\right.\) (T/M)
