B)-3x+8=5x+16

C)x-4+5x=4x-8​

Answer 1

Resposta:

A)7x-6x=-5-10

x=-5

B)-3x-5x=16-8

-2x=8

x=8÷-2

x=-4

C)x+5x-4x=-8+4

2x=-4

x=-4÷2

x=-2

Answer 2

Oi....

a)

7x + 10 = 6x  -5

7x - 6x = - 5 - 10

x = - 15

b)

- 3x + 8 = 5x + 16

- 3x - 5x = 16 - 8

- 8x = 8 ⇒ ( - 1)

8x = - 8

x = - 8/8

x = - 1

c)

x - 4 + 5x = 4x - 8

6x - 4 = 4x - 8

6x - 4x = - 8 + 4

2x = - 4

x = - 4/2

x = - 2​

Espero ter ajudado.
