Question

ayudenme con este ejercicio porfavor 0.6x-0.3=1.2+0.4x las x son los signos de ingconicta

Answer 1

$0.6x-0.3=1.2+0.4x\\0.6x-0.4x=1.2+0.3\\0.2x=1.5\\x=\frac{1.5}{0.2}\\ x=7.5$

$\frac{6}{10} x-\frac{3}{10}=\frac{12}{10}+\frac{4}{10}x \\\frac{6}{10} x-\frac{4}{10}x=\frac{12}{10}+\frac{3}{10}\\\frac{6-4}{10} x=\frac{12+3}{10}\\\frac{2}{10} x=\frac{15}{10}\\x=\frac{15*10}{2*10}=\frac{15}{2} =7\frac{1}{2} =7.5$
