Question

Помогите пожалуйста решить!

Answer 1

1)
$x = \frac{ - 7 \times 24}{8} = \frac{ - 7 \times 3 \times 8}{8} = - 21$
2)
$x = \frac{10 \times ( - 9) }{5} = 2 \times ( - 9) = - 18$
3)
$x = \frac{ - 6 \times ( - 5)}{1.2} = \frac{30}{1.2} = 25$
4)
$x = \frac{20 \times ( - 3.5)}{4} = 5 \times ( - 3.5) = - 17.5$
5)
$x = \frac{15 \times ( - 1.9)}{3} = 5 \times ( - 1.9) = - 9.5$
6)
$- y = \frac{ - 7 \times 20.5}{4.1} = - 35 \\ y = 35$
