Question

2-|3/4-x|=7/8

 

Answer 1

\(!\frac{3}{4}-x!=2-\frac{7}{8}=\frac{9}{8}\)

\(x-\frac{3}{4}=\frac{9}{8}\Rightarrow x=\frac{15}{8}\)

\(x-\frac{3}{4}=-\frac{9}{8}\Rightarrow x=-\frac{3}{8}\)

2.I3-4xI=9

\(\orbr{\begin{cases}3-4x=\frac{9}{2}=>x=\frac{-3}{8}\\3-4x=-\frac{9}{2}=>x=\frac{15}{8}\end{cases}}\)
