Question

Resolva essas equações 10x-8=15x
-4+22=10x
16-4x=-4

Answer 1

10x - 8 = 15x
10x - 15x = 8
- 5x = 8
x = - 8/5

----------------

- 4 + 22 = 10x
18 = 10x
x = 18/10 => Dividindo numerador e denominador por 2
x = 9/5

----------------------------------

16 - 4x = - 4
- 4x = - 4 - 16

-4x = - 20
x = -20/(-4)
x = 5

Answer 2

10x-8=15x

10x - 15x = 8

- 5x = 8 ( - 1)

5x = - 8

x= - 8/5

-4+22=10x

18 = 10x

x= 18/10 ( ÷ 2)

x= 9/5

16-4x=-4

- 4x = - 4 - 16

- 4x = - 20

x= - 20/-4

x= 5
