Question

Dada a equação 2x/4 - 5/3 = x - 7/2 Qual o valor de x?​

Answer 1

Resolução:

$\frac{2x}{4} - \frac{5}{3} = x - \frac{7}{2}$

$\frac{x}{2} - \frac{5}{3} -x = -\frac{7}{2}$

$\frac{x}{2} -x = -\frac{7}{2} + \frac{5}{3}$

$\frac{x}{2} - \frac{2x}{2} = -\frac{21}{6} + \frac{10}{6}$

$\frac{x - 2x}{2} = \frac{-21 +10}{6}$

$\frac{-x}{2} = \frac{-11}{6}$

$\frac{x}{2} = \frac{11}{6}$

$x = \frac{11.2}{6}$

$x = \frac{11}{3}$
