Question

-X -1=7
-3x +40=10
-X -6=3
-x -8=0

algm me ajuda nessas pfv ​

Answer 1

Resposta:

-x - 1 = 7

-x = 7 + 1

-x = 8

x = 8/-1

x = -8

-3x + 40 = 10

-3x = 10 - 40

-3x = -30

x = -30/-3

x = 10

-x - 6 = 3

-x = 3 + 6

-x = 9

x = 9/-1

x = -9

-x - 8 = 0

-x = 0 + 8

-x = 8

x = 8/-1

x = -8

Answer 2

Resposta:

1) -x-1=7

-x=7+1

(-1) -x=8 o (-1) está multiplicando o (-x) para retirar o sinal

x=8

2)-3x+40=10

-3x=10-40

-3x=-30

x=-30/-3

x=10

3)-x-6=3

-x=3+6

-x=9

(-1)-x=9

x=9

4)-x-8=0

-x=8

(-1)-x=8

x=8
