Answer 1

Explicação passo-a-passo:

d - 4 + 8 x = - 68

8x=-68+4

8x=-64

x=-8

E 2(x-4)=4

2x-8=4

2x=4+8

2x=12

x=6

F 1-3(x4)=1

1-3x-12=1

-3x=12-1+1

-3x=12

-x=4

(-1)•(-x)=4•(-1)

x=-4

G 4x-10+8x=50

12x=50+10

12x=60

x=5

H 2(x-9)+4x=-36

2x-18+4x=-36

6x=-36+18

6x=-18

x=-3

I -15=3(x-1)+2x

-15=3x-3+2x

-15=5x-3

-15+3=5x

-12=5x

x=-12/5

J 1+2x-(2-3x)=-21

1+2x-2+3x=-21

5x=-21+1

5x=-20

x=-4

K 2(7x-1)-3(4-14x)=-6

14x-2-12+42x=-6

56x-14=-6

56x=-6+14

56x=8

x=8/56

x=1/7

L -61=2(x+7)-3(3-3x)

-61=2x+14-8+9x

-61=11x+6

-61-6=11x

-67=11x

x=67/11

M 4x=x-9

4x-x=-9

3x=-9

x=-3
