-1+8(7-6х)= 2х+6
-1+56-48х= 2х+6
-48х-2х= 6+1-56
-50х= -49
х= -49:(-50)
х= 0,98

-2+3(1+2х)= -2х+3
-2+3+6х= -2х+3
6х+2х= 3+2-3
8х= 2
х= 2:8
х= 0,25

-3х+4= -10+5(-7-х)
-3х+4= -10-35-5х
-3х+5х= -10-35-4
2х= -49
х= -49:2
х= -24,5

3х-10= 2+6(5+4х)
3х-10= 2+30+24х
3х-24х= 2+30+10
-21х= 42
х= 42:(-21)
х= -2

5х-4= 4-3(5-2х)
5х-4= 4-15+6х
5х-6х= 4-15+4
-х= -7
х= 7

4-2(5+4х)= -х+1
4-10-8х= -х+1
-8х+х= 1-4+10
-7х= 7
х= 7:(-7)
х= -1

10-3(1-7х)= -4х-8
10-3+21х= -4х-8
21х+4х= -8-10+3
25х= -15
х= -15:25
х= -0,6

-1-4(-7+8х)= -2х-6
-1+28-32х= -2х-6
-32х+2х= -6+1-28
-30х= -33
х= -33:(-30)
х= 1,1

5(5+3х)-10х= 8
25+15х-10х= 8
15х-10х= 8-25
5х= -17
х= -17:5
х= -3,4

4(7+х)-3х= 7
28+4х-3х= 7
4х-3х= 7-28
х= -21

7(-5+3х)+4х= 9
-35+21х+4х= 9
21х+4х= 9+35
25х= 44
х= 44:25
х= 1,76

X'+2xy=-xe^-x^2 sin x, y=(0)
