Question

Calcule o valor de x em: x + (1/2 + 5/2) : 3/2 + ( 7/4 + 1/4) =0

Answer 1

$x + ( \frac{1}{2} + \frac{5}{2} ) : \frac{3}{2} + ( \frac{7}{4} + \frac{1}{4} ) =0 \\ \\ x + ( \frac{1+5}{2} ) : \frac{3}{2} + ( \frac{7+1}{4} ) =0 \\ \\ x + ( \frac{6}{2} ) : \frac{3}{2} + ( \frac{8}{4} ) =0 \\ \\ x + 3 : \frac{3}{2} + 2 =0 \\ \\ x + 3 \cdot \frac{2}{3} + 2 =0 \\ \\ x + 2 + 2 =0 \\ \\ x+4=0 \\ \\ x=-4$
