1 /2 x + 3 = ( 3/2 + 1/4 )

Answer 1

$\frac{1}{2}x+3=\left(\frac{3}{2}+\frac{1}{4}\right)$

$\frac{1}{2}x+3=\frac{3\cdot \:2}{4}+\frac{1}{4}$

$\frac{1}{2}x+3=\frac{2\cdot \:3+1}{4}$

$\frac{1}{2}x+3=\frac{7}{4}$

$\frac{1}{2}x+3-3=\frac{7}{4}-3$

$\frac{1}{2}x=-\frac{5}{4}$

$2\cdot \frac{1}{2}x=2\left(-\frac{5}{4}\right)$

$x=-\frac{5}{2}$

$Respuesta:-\frac{5}{2} Espero que te sirva. :)$
