Question

x/1-x/7=-3/1 calculo urgenteee pra hoje

Answer 1

$\frac{x}{1} -\frac{x}{7} = - \frac{3}{1}$

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

7x-x=-21

6x=-21

x= - $\frac{21}{6}$

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

Answer 2

x - x/7 = -3 (Apliquei um mmc de 7 e 1)

6x/7 = -3

6x= -3.(7)
6x= -21
x= -21/6 (simplificando)

x= -7/2
