Answer 1

Ответ:

4n-2=6n+5

4n-6n=2+5

-2n=7

n=-3,5

-7-4x=-7x+5

-4x+7x=5+7

3x=12

x=4

Answer 2

$4n - 2 = 6n + 5 \\ 4n - 6n = 5 + 2 \\ - 2n = 7 \\ n = 7 \div ( - 2) \\ n = - 3.5 \\ = = = = = = = = = = = = =$

$- 7 - 4x = - 7x + 5 \\ - 7 - 5 = - 7x + 4x \\ - 12 = - 3x \\ - 3x = - 12 \\ x = 12 \div 3 \\ x = 4$
