Question

Решите уравнение:
1)-4х=-10х-9

2)6+3х=4х-1

3)-1+2х=10х+3

4)-4+3х=8х+5

5)9+4х=8х-9

6)2+8х=3х+9

7)6-2х=3х-10

Answer 1

1)-4x+10x=-9
6x=-9
x=-9/6=-3/2
2)3x-4x=-1-6
-x=-7
x=7
3)2x-10x=3+1
-8x=4
x=-4/8=-1/2
4)3x-8x=5+4
-5x=9
x=-1 4/5
5)4x-8x=-9-9
-4x=-18
x=4 5/4
6)8x-3x=9-2
5x=6
x=6/5= 1 1/5
7)-2x-3x=-10-6
-5x=-16
x=3 1/5

Answer 2

1.
-4х = -10х - 9
-4х +10х = -9
6х = -9
х = -1.5

2.
6+3х=4х-1
3х-4х=-1-6
-х=-7
х=7

3.
-1+2х=10х+3
2х-10х=3+1
-8х=4
х=-0.5

5.
-4+3х=8х+5
3х-8х=5+4
-5х=9
х=-1.8

6.
2+8х=3х+9
8х-3х=9-2
5х=7
х=1.4

7.
6-2х=3х-10
-2х-3х=-10-6
-5х=-16
х=3.2
