Answer 1

Respuesta:

a ) x = 3 / 8

b ) x = 4

c ) x = 1

d ) x = 12

Explicación paso a paso:

a )

2x + 1 = - 6x - 4

2x + 6x = 4 - 1

8x = 3

x = 3 / 8

b )

x + 9 = 3x + 1

3x + 1 = x + 9

3x - x = 9 - 1

2x = 8

x = 8 / 2

x = 4

c )

8x - 3 = 10x - 5

10x - 5 = 8x - 3

10x - 8x = - 3 + 8

2x = 2

x = 2 / 2

x = 1

d )

6x - 4 = 5x + 8

6x - 5x = 8 + 4

x = 12
