Ответ:
1) -7; 2)2; 3)0,5; 4)5
Пошаговое объяснение:
1) 6x - 3 = 5x +5 - 10
6x - 5x = 3 - 10
x = -7
2) 8x - 6 - 5x = 12x - 24
8x - 5x - 12x = 6 - 24
-9x = -18
x = -18/-9
x = 2
3) 2x + 13 = 4 - 8x + 14
2x +8x = 4 - 13 +14
10x = 5
x = 5/10
x = 0,5
4) 6x - 6 +14x +21 = 105 + 2x
6x + 14x -2x = 6 - 21 + 105
18x = 90
x = 90/18
x = 5
1) 3(2х-1)=5(х+1)-10
6х-3=5х+5-10
6х-5х= 5-10+3
1х= -2
х= -2:1
х= -2
2)2(4х-3)-5х=12х-24
8х-6-5х=12х-24
8х-5х-12х=-24+6
-9х=-18
х= -18: -9
х=2
3)2х+13=4(1-2х)+14
2х+13=4-8х+14
2х+8х=14+4-13
10х= 5
х= 5:10
х=0.5
4) 6(х-1)+7(2х+3)=105+2х
