Explicație pas cu pas:
[tex]\frac{1}{2}x=\frac{7}{4}+\frac{2}{3}\\ \frac{1}{2}x=\frac{7*3+2*4}{4*3}=\frac{21+8}{12}=\frac{29}{12}\\ x=\frac{29}{12}*2=\frac{29}{6}[/tex]
[tex]- \frac{x}{3} =\frac{9}{2} -\frac{7}{4} \\- \frac{x}{3}=\frac{11}{4} \\x=-\frac{33}{4}[/tex]
[tex]\frac{5x}{3}-\frac{x}{2}= \frac{4}{9} +\frac{2}{3} \\\frac{7x}{6} =\frac{10}{9} \\[/tex], x=60/63=20/21
[tex]x-\frac{3}{2} =[/tex]±[tex]\frac{4}{15}[/tex]
[tex]x-\frac{3}{2} = \frac{4}{15} \\x1=\frac{4}{15} +\frac{3}{2} =\frac{53}{30}[/tex]
[tex]x2=-\frac{4}{15}+\frac{3}{2} =\frac{37}{30}[/tex]
