C)3+3x-1=x+2+2x
D)2(3x-2)=2
E)5-2(1-x)=2x-3
ME AYUDAN!!!

Answer 1

Explicación paso a paso:

A) - x=x-8-2

- x=x-10

- 2x=-10

X = 5

B) 2x - 1 = 5x +8

- 1 - 8 = 5x - 2x

- 9 = 3x

- 3 = x

C) 3+ 3x - 1 = X +2 +2x

2 + 3x = 3x +2

3x - 3x = 2 - 2

0 = 0

D) 2(3x - 2) =2

6x - 4 = 2

6x = 2 + 4

6x = 6

X = 1

E) 5-2(1-x) = 2x - 3

5 - 2 + 2x = 2x - 3

3 + 2x = 2x - 3

2x - 2x = - 3 - 3

0 = - 6

Recuerda que

(+) (-) = (-)

(-) (-) = (+)

Answer 2

Respuesta:

$A ) 2 - x = x - 8\\- x - x = - 8 - 2\\-2x = - 10\\x = - 10 / - 2\\x = 5\\\\B ) 2x - 1 = 5x + 8\\2x - 5x = 8 + 1\\- 3x = 9\\x = 9 / - 3\\x = - 3\\\\ C ) 3 + 3x - 1 = x + 2 + 2x \\3x - x - 2x = 2 - 3 + 1\\0 = 0\\\\\\D) 6x - 4 = 2\\6x = 2 + 46x = 6\\x = 6 / 6\\x = 1\\\\E ) 5 - 2 - 2x = 2x - 3\\- 2x - 2x = - 3 - 5 + 2\\- 4x = - 6\\ \\\\\\ x = 1.5x = - 6 / - 4$
