alguém responde pelo amor de Deus!​

Answer 1

e)$\frac{7}{x} + \frac{3}{x {}^{2} } - \frac{1}{2x} \\ \frac{14x + 6 - x}{2x {}^{2} } \\ \frac{13x + 6}{2x {}^{2} }$

FranxxDarling Responde

a)

$\frac{5}{3x} + \frac{7}{4x} \\ \frac{4 \times 5}{4 \times 3x} + \frac{3 \times 7}{3 \times 4x} \\ \frac{20}{12x} + \frac{21}{12x} \\ \frac{41}{12x}$

b)

$\frac{y}{5a} - \frac{2y}{a} \\ \frac{y}{5a} - \frac{5 \times 2y}{5a} \\ \frac{y}{5a} - \frac{10y}{5a} \\ - \frac{9y}{5a}$

d)

$\frac{a}{2y} + \frac{3}{xy} \\ \frac{xa}{x \times 2y} + \frac{3 \times 3}{2xy} \\ \frac{ax + 6}{2xy}$

c)2y×4/2y×3x + 3xa/3x×2y

8y/6xy + 3ax/6xy

8y+3ax/6xy

Espero ter ajudado tenha uma boa tarde
