Помогите решить уравнения: 1) - (3y+7) = 8-2 (8-y) ;

2) - 2 (2-5x) = 2 (x-3) - 5;

3) 4x-2 (x+7) = 2 (3-x) ;

4) 2x-4 (x+7) = 3 (2-x) ;

5) 1,24x+3,46=1,76x+6,58;

6) - 4,92y - (0,08y+5,12) = - 0,88-y;

7) 1,26x+3,58=1,74x+6,46;

8) 0,88 - (5,12+0,08y) = 4,92y-y.

1) - 3y-7=8-16+2y

-3y-2y=8-16+7

-5y=-1

y=0,2

2) - 4+10x=2x-6-5

10x-2x=4-6-5

8x=-7

x=-0.875

3) 4x-2x-14=6-2x

4x=20

x=5

4) 2x-4x-28=6-3x

x=34

5) - 0,52x=3.12

x=-6

6) - 4.92y-0,08y-5.12=-0.88-y

-5y+y=6

-4y=6

y=1.5

7) 1.26x-1.74x=6.46-3.58

-4.8x=2.88

x=-0,6

8) 0.88-5.12-0.08y=4.92y-y

0.88-5.12=4y

-4.24=4y

y=-1.06

1) - 3y-7=8-16+2y

-3y-2y=8-16+7

-5y=-1

y=0.2

2) - 4+10x=2x-6-5

10x-2x=-6-5+4

8x=-7

x=-7/8

3) 4x-2x-14=6-2x

0x=20

x=0 нет корней!

4) 2x-4x-32=6-3x

2x-4x+3x=6+32

x=38
