Question

1) Calcule o valor de X:
a) 30/x = 6
b) – 2 = 8/x
c) 1 + 3/x = -2​

Answer 1

a)  $\frac{30}{x} =6$

30 = 6x

6x = 30

$x=\frac{30}{6}$

x = 5

b) $-2=\frac{8}{x}$

- 2 . x = 8

$x=\frac{8}{-2}$

x = - 4

$c)1+\frac{3}{x} =-2$

1+ 3 = - 2 . x

4 = - 2x

- 2x = 4

$x=\frac{4}{-2}$

x = - 2
