Question

помогите пожалуйста 9x -7=6x+14 и 3(4-2x)+6=-2x+4

Answer 1

9x-7=6x+14

9x-6x=14-7

3x=7

x=7/3

x=2 1/3

3(4-2x)+6=2x+4

12-6x+6=2x+4

-6x-2x=4-12-6

-8x=-14

x=-14/-8

x=1,75

Answer 2

$9x - 7 = 6x + 14 \ 9x - 6x = 14 + 7 \ 3x = 21 div 3 \ x = 7 \ \ 3(4 - 2x) + 6 = 2x + 4 \ 12 - 6x + 6 = 2x + 4 \ 18 - 6x = 2x + 4 \ 18 - 6x - 2x = 4 \ - 6x - 2x = 4 - 18 \ - 8x = - 14 div - 8 \ x = 1.75$
