Question

y+4(2y+1)= 8+2y -1
8x -15=2 (x+6)

Answer 1

Respuesta:

y=3/7

x=27/6 o 4,5

Explicación paso a paso:

1)

y+4(2y+1)=8+2y-1

y+8y+4=8+2y-1

9y+4=8+2y-1

9y-2y=8-1-4

7y=3

y=3/7

2)

8x-15=2(x+6)

8x-15=2x+12

8x-2x=15+12

6x=27

x=27/6

Answer 2

Respuesta:

y + 4 ( 2y + 1 ) = 8 + 2y - 1

y + 8y + 4 = 8 + 2y - 1

y + 8y - 2y = 8 - 1 - 4

9y - 2y = 7 - 4

7y = 3

y = 3/7

8x - 15 = 2 ( x + 6 )

8x - 15 = 2x + 12

8x - 2x = 12 + 15

6x = 27

x = 27/6

x = 9/2
