2-. 4x+1=2x+11
3-. 5x-5=3x+9
4-. 15x-1=12x+2

Valor de la X?? :(

Answer 1

Respuesta:

1.- x = 2

2.- x = 5

3-. x = 7

4.- x = 1

Explicación paso a paso:

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

5x - 2x = 4 + 2

3x = 6

x = 6/3

x = 2

2.- 4x + 1 = 2x+ 11

4x - 2x = 11 - 1

2x = 10

x = 10/2

x = 5

3-. 5x - 5 = 3x + 9

5x - 3x = 9 + 5

2x = 14

x = 14/2

x = 7

4-. 15x - 1 = 12x + 2

15x - 12x = 2 + 1

3x = 3

x = 3/3

x = 1
