Question

Resolva as equações de 1 grau

1) 6x+8=-3x-22

2) 3(x+2)=4x-9

3) 6(x-3)=4(x+2)

Answer 1

1)

6x + 8= - 3x - 22

6x + 3x= - 22 - 8

9x= - 30

x= -30/ 9

2)

3(x+2)= 4x - 9

3x + 6= 4x - 9

3x - 4x= - 9 - 6

- 1x= - 15

x= -15/ -1

x= 15

3)

6(x - 3)= 4(x + 2)

6x - 18= 4x + 8

6x - 4x= 8 + 18

2x= 26

x= 26/ 2

x= 13
