Question

solver los siguientes ejercicios 2-x=x-8 , 2x-1=5x+8, x-5(2x_3)=3(x-1)+4, 3(x+4)+10=x.​

Answer 1

1 ) 2 - X = X - 8

- X - X = - 8 - 2

- 2 X = - 10 ( - 1 )

2 X = 10

X = 10 / 2

X = 5

2 ) 2 X - 1 = 5 X + 8

2 X - 5 X = 8 + 1

- 3 X = 9 ( - 1 )

3 X = - 9

X = - 9 / 3

X = - 3

3 ) X - 5 ( 2 X - 3 ) = 3 ( X - 1 ) + 4

X - 10 X + 15 = 3 X - 3 + 4

X - 10X - 3 X = - 3 + 4 - 15

12 X = - 14

X = 14 / 12 = 7 / 6

X = 7 / 6

4 ) 3 ( X + 4 ) + 10 = X

3 X + 12 + 10 = X

3 X - X = - 10 - 12

2 X = - 22

X = - 22 / 2

X = - 11
