Question

решите уравнение 4(3(2x-1)+7)-4=3(3(2x-1)+6)

Answer 1

4(3(2x-1)+7)-4=3(3(2x-1)+6

4(6x-3+7)-4=3(6x-3+6)

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

24x+16-4=18x+9

24x+12=18x+9

24x-18x=9-12

6x=-3

x=-1/2

или же х=-0.5

Answer 2

Ответ:

4(3(2x-1)+7)-4=3(3(2x-1)+6)

4(6x-3+7)-4=3(6x-3+6)

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

24x+16-4=18x+9

24x+12=18x+9

24x-18=9-12

6x=-3

$x = frac{1}{2}$

x1=0,5 ;

$x2 = -{2}^ - {1}$

Вроде так
