Question

21 – 6x = 27 - 8x

8x – 4 + 3x = 7x + x + 14

16 + 7x – 5 + x = 11x – 3 - x ayudaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa es para oy

Answer 1

Respuesta:

1) X=3

2) X=6

3) X=7

Explicación paso a paso:

21 – 6x = 27 - 8x

21-27 = -8X +6X

-6 = -2X

X=3

8x – 4 + 3x = 7x + x + 14

11X-4 = 8X+14

11X-8X = 14+4

3X= 18

X= 6

16 + 7x – 5 + x = 11x – 3 - x

8X + 11 = 10X-3

11+3 =10X -8X

14 = 2X

7=X

Answer 2

Explicación paso a paso:

21 – 6x = 27 - 8x

-6x+8x=27-21

2x=6

x=6/2

x=3

8x – 4 + 3x = 7x + x + 14

8x+3x-7x-x=14+4

3x=18

x=18/3

x=6

16 + 7x – 5 + x = 11x – 3 - x

7x+x-11x+x=-3-16+5

2x=-14

x=-14/2

x=-7
