Question

X/3 = 5


2x/7= -6


x5 = - 2


5x/12 = 2/6

​

Answer 1

Explicação passo-a-passo:

$a) \frac{x}{3} = 5 \\ x = 3.5 \\ x = 15$

$b) \frac{2x}{7} = - 6 \\ 2x = 7. - 6 \\ 2x = - 42$

$x = \frac{ - 42}{2}$

$x = - 21$

$c)5x = - 2 \\ x = - \frac{2}{5}$

$d) \frac{5x}{12} = \frac{2}{6}$

$30x = 2.12$

30x=24

x=24/30 :(6/6)

x=4/5
