Question

2(3/4-5x)=4/5-3x

Answer 1

\(2\left(\frac{3}{4}-5x\right)=\frac{4}{5}-3x\)

\(\frac{3}{2}-10x=\frac{4}{5}-3x\)

\(-10x+3x=\frac{4}{5}-\frac{3}{2}\)

\(-7x=-\frac{7}{10}\)

\(x=-\frac{1}{10}\)

Answer 2

Cold Wind chế sai rồi -7x và -7/10 âm

=>x dương chứ

Answer 3

\(\Leftrightarrow\frac{3}{2}-10x=\frac{4}{5}-3x\)

\(\Leftrightarrow\frac{7}{10}-7x=0\)

\(\Leftrightarrow7x=\frac{7}{10}\)

\(\Leftrightarrow x=\frac{1}{10}\)
