Answer 2

Răspuns:

Explicație pas cu pas:

$\frac{1}{2}x=\frac{7}{4}+\frac{2}{3}\\ \frac{1}{2}x=\frac{7*3+2*4}{4*3}=\frac{21+8}{12}=\frac{29}{12}\\ x=\frac{29}{12}*2=\frac{29}{6}$

$- \frac{x}{3} =\frac{9}{2} -\frac{7}{4} \\- \frac{x}{3}=\frac{11}{4} \\x=-\frac{33}{4}$

$\frac{5x}{3}-\frac{x}{2}= \frac{4}{9} +\frac{2}{3} \\\frac{7x}{6} =\frac{10}{9}$, x=60/63=20/21

$x-\frac{3}{2} =$±$\frac{4}{15}$

$x-\frac{3}{2} = \frac{4}{15} \\x1=\frac{4}{15} +\frac{3}{2} =\frac{53}{30}$

$x2=-\frac{4}{15}+\frac{3}{2} =\frac{37}{30}$
