Question

ркшите уравнение пожалуйста​

Answer 1

Ответ:

$1)5x = - 10 \\ x = - 10 \div 5 \\ x = - 2$

$2) - x = 0.5 \\ x = 0.5 \times ( - 1) \\ x = - 0.5$

$3) - 2.2x = - 5.5 \\ x = - 5.5 \div ( - 2.2) = 55 \div 22 \\ x = 2.5$

$4)1 \frac{2}{3} x = - \frac{5}{3} \\ x = - \frac{5}{3} \div \frac{5}{3} \\ x = - 1$
