Question

Tim x :x-3/2=3x+1/4

Answer 1

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

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

\(-2x=\frac{7}{4}\)

\(x=\frac{7}{4}:\left(-2\right)\)

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

Answer 2

Tìm x : 

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

\(\Leftrightarrow x-3x=\frac{1}{4}+\frac{3}{2}\)

\(\Leftrightarrow1x-3x=\frac{1}{4}+\frac{6}{4}\)

\(\Leftrightarrow-2x=\frac{7}{4}\)

\(\Leftrightarrow x=\frac{7}{4}:\left(-2\right)\)

\(\Leftrightarrow x=\frac{7}{4}.\frac{-1}{2}\)

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