Question

Calcule: a) (2/3x - 2y) – (1/2y - 1/2x) = b) (1/3 +y) + (1/4x - 3/2y) =.

Answer 1

Resposta:

a) $\frac{7}{6} x - \frac{5}{2} x$

b) $-\frac{1}{2} +\frac{1}{4} x + \frac{1}{3}$

Explicação passo a passo:

a) $(\frac{2x}{3} -2y) - (-\frac{1}{2}x+ \frac{1}{2} y)$ = $\frac{7}{6} x - \frac{5}{2} x$

b)

$(y+\frac{1}{3} ) + (-\frac{3}{2}y+\frac{1}{4} y)=\\\\-\frac{1}{2} +\frac{1}{4} x + \frac{1}{3}$

posso ter melhor resposta?
