Question

6-x-1/2=3-x/2+x-2/3 решите уравнение

Answer 1

6-x-1/2=3-x/2+x-2/3 
6-1/2-3+2/3=-х/2+х+х
3-1/2+2/3=-х/2+2х
3-3/6+4/6=3/2*х
3 1/6=3/2*х
х=19/6:3/2=(19*2)/(6*3)
х=19/9=2 1/9

Answer 2

6 - x - 1/2 = 3 - x/2 + x - 2/3
3 - x - 1/2=x-x/2 - 2/3   (домножаем на 6)
18 - 6x - 3= 6x -3x -4
15 - 6x=3x -4
9x=19
x=19/9
