Question

resolva 3x=-9. -4x=20. 18x=24. -30x=10. x/6=-14. -4x/7=15. 3x/8=-6. -5x/11=-10​

Answer 1

3x=-9

x= - 9/3

x= - 3

-4x=20.

x = 20/-4

x= - 5

18x=24

x= 24/18 (÷6)

x= 4/3

-30x=10(-1)

30x = - 10

x= - 10/30 (÷10)

x= - 1/3

x/6=-14

x= - 14 • 6

x= - 84

-4x/7=15.

- 4x= 15 • 7

-4x = 105

x = 105/-4

x= - 26,25

3x/8=-6.

3x = - 6 • 8

3x= - 48

x= - 48/3

x= - 16

-5x/11=-10

- 5x = - 10 • 11

- 5x = - 110

x= - 110/-5

x= 22
