Question

a)5x=8x+10
c)2(x+1)-10=5(5x-1)
b)3x-1=5
d)-3-4x=2​

Answer 1

Olá...

a)

5x = 8x + 10

5x - 8x = 10

- 3x = 10 ⇒( - 1)

3x = - 10

x = - 10/3

b)

2(x + 1) - 10 = 5(5x - 1)

2x + 2 - 10 = 25x - 5

2x - 8 = 25x - 5

2x - 25x = - 5 + 8

- 23x = 3⇒ ( - 1)

23x = - 3

x = - 3/23

c)

3x - 1 = 5

3x = 5 + 1

3x = 6

x = 6/3

x = 2

d)

- 3 - 4x = 2

- 4x = 2 + 3

- 4x = 5⇒( - 1)

4x = - 5

x = - 5/4

Espero ter ajudado​

Answer 2

Resposta:

5x=8x+10

-10=8x-5x

-10=3x

x=-10/3

x=-3,3

2(x+1)-10=5(5x-1)

2x+2-10=25x-5

5+2-10=25x-2x

x=-3/23

-0,1

3x-1=5

3x=5+1

x=6/3

x=2

-3-4x=2

-3-2=4x

-5=4x

x=-5/4

x=-1,25
