Answer 1

Пошаговое объяснение:

1) 18 - 6x = 20 + 8x

-6x - 8x = 20 - 18

x =2 / -14 = $- \frac{1}{7}$

2) 4 + 8x = 30 - 10x

8x + 10x = 30 - 4

x = 26 /18 = $\frac{13}{9}$

3) 12 - 6x = 15 - 20x

-6x + 20x = 15 - 12

x = $\frac{3}{14}$

4) 14 - 6x = 24 - 12x

-6x + 12x = 24 - 14

x = 10 / 6 = $\frac{5}{3}$
