Question

03-dada a equação 2x/4-5/3=x-7/2,calcule o valor de x.

;)

Answer 1

Resposta:

$\frac{2x}{4} - \frac{5}{3} = x - \frac{7}{2} \\ \frac{6x}{12 } - \frac{20}{12} = \frac{12x}{12} - \frac{42}{12} \\ 6x - 20 = 12 x - 42 \\ 6x - 12x = - 42 + 20 \\ - 6x = - 22 \\ x = \frac{22}{6} = \frac{11}{3}$
