Question

a) 6 ( x - 1/2 ) = 2x - 1

b) 5 (x + 1 ) – x = 4 x + 15

c) 2 x = 2 ( x + 1) - 2

Answer 1

Explicación paso a paso:

a) 6 ( x - 1/2 ) = 2x - 1.

6x - 6/2 = 2x -1

6x - 3 = 2x - 1

4x = 2

x = 2/4

x = 1/2

b) 5 (x + 1 ) – x = 4 x + 15

5x + 5 - x = 4x + 15

4x + 5 = 4x + 15

0x = 10

¿? no has puesto mal algo?

c) 2 x = 2 ( x + 1) - 2

2x = 2x + 2 - 2

0x = 0
