Question

Resuelve las siguientes ecuaciones: 1.- x + 10 = 3 2.- x – 4 = 2 3.- 2 – x = 4 4.- 3x – 5 = 1 5.- 19 + 3x = 3 – 5x 6.- 3x + 5 – x = 5x + 3x – 4 7.- 5x – 2 + x = 6x + 2 8.- 6x – 4 – 4x = 1 + 2x – 5 9.- 3 + 2·(2x – 3) = 4x – (x+3) 10.- 2/5 x 2/1 . me urge!

Answer 1

1.

x + 10 = 3

x = 3 - 10

x = -7

2.

x - 4 = 2

x = 2 -4

x = -2

3.

2 - x = 4

2 - 4 = x

-2 = x

4.

3x -5 = 1

3x = 1 + 5

x = 6 : 3

x = 2

5.

19 + 3x = 3

3x = 3 - 19

x = -16/3

6.

3x + 5 - x = 5x + 3x -4

5 + 4 = 5x + 3x -3x + x

9 = 6x

9 : 6 = x

1,5 = x

7.

5x - 2 + x = 6x + 2

-2 -2 = 6x - 5x - x

-4. 0 = x

0 = x

8.

6x - 4 - 4x = 1 + 2x - 5

6x - 4x - 2x = 1 - 5 + 4

x = 0.0

x = 0

la 9 y 10 no las sé
