Answer 1

Explicação passo-a-passo:

a

10x-11=-1

10x=-1+11

10x=10

x=10/10

x=1

b

3x/7=6

3x=6.7

3x=42

x=42/3

x=14

c

6x-18=-6

6x=-6+18

6x=12

x=12/6

x=2

d

4x+3=-5

4x=-5-3

4x=-8

x=-8/4

x=-2

E

3x-2=4x+9

3x-4x=9+2

-x= 11

x=11/-1

x=-11

f

7x+5-x+8=31

7x-x=31-8-5

6x= 23-5

6x=18

x=18/6

x=3

g

15-10x=55

-10x=55-15

-10x=40

x=40/-10

x=-4

h

9x+1=2x+50

9x-2x=50-1

7x= 49

x=49/7

x=7

i

4x-1=11+x

4x-x=11+1

3x=12

x=12/3

x=4

j

x-3=6+4x

x-4x=6+3

-3x=9

x=9/-3

x=-3

k

3x-6=12

3x=12+6

3x=18

x=18/3

x=6

l

x+1=8

x=8-1

x=7
