Doy coronitaaaaaaa pero aiudaaa​​

Answer 1

3x + 2x - 4 = 6

5x = 6 + 4

5x  =10

x = 10/5

x = 2

7x - 2x + 20 = -20

5x = -20 - 20

5x = -40

x = - 40/5

x = -8

8x - 3x - 6 = 4

5x = 6 + 4

5x = 10

x = 10/5

x = 2

x - 4x = 3

-3x = 3

3  = 3x

3/3 = x

1 = x

-2x - 4x - 2 = 1

-6x = 2 - 1

-6x = 1

-1 = 6x

-1/6 = x
