Question

x/4+5/2=x/3 - 1/2
comprobación por fa

Answer 1

$\frac{x}{4} + \frac{5}{2} = \frac{x}{3} - \frac{1}{2} \\ 12( \frac{x}{4} + \frac{5}{2} ) = 12( \frac{x}{3} - \frac{1}{2} ) \\ 3x + 30 = 4x - 6 \\ 30 + 6 = 4x - 3x \\ 36 = x$

Comprobación:

$\frac{36}{4} + \frac{5}{2} = \frac{36}{3} - \frac{1}{2} \\ 9 + \frac{5}{2} = 12 - \frac{1}{2} \\ 9 + 2.5 = 12 - 0.5 \\ 11.5 = 11.5$
