ME AJUDEM:equação do 1 grau

A) -X+3=4
B)-X-2=-5
C)9-5X=0
D)7-8X=-1
E)8-3X=-5
F)10+4X=10

Answer 1

A) -X+3=4

- x= 4 - 3

- x= 1 ( - 1)

x= - 1

B)-X-2=-5

- x= - 5 + 2

- x= - 3 ( - 1)

x= 3

C)9-5X=0

- 5x = 0 - 9

- 5x= - 9 ( - 1)

5x= 9

x= 9/5

D)7-8X=-1

- 8x = - 1 - 7

- 8x= - 8 ( - 1)

8x= 8

x= 8/8

x= 1

E)8-3X=-5

- 3x = - 5 - 8

- 3x= - 13 ( - 1)

3x= 13

x= 13/3

F)10+4X=10

4x = 10 - 10

4x= 0

x= 0/4

x= 0
