\(\dfrac{{5x - 3}}{4} = \dfrac{{x + 2}}{3}\)
\(\dfrac{{\left( {5x - 3} \right).3}}{{4.3}} = \dfrac{{\left( {x + 2} \right).4}}{{3.4}}\)
\(\dfrac{{15x - 9}}{{12}} = \dfrac{{4x + 8}}{{12}}\)
\(15x - 9 = 4x + 8\)
\(15x - 4x = 8 + 9\)
\(11x = 17\)
\(x = 17:11\)
\(x = \dfrac{{17}}{{11}}\)
Vậy phương trình có nghiệm \(x = \dfrac{{17}}{{11}}\).
