Verified answer

Explicación paso a paso:

x + 5 = 14x

x - 14x = -5

-13x = -5

x = 5/13

comprobación:

5/13 + 5 = 14 (5/13)

70/13 = 70/13

4x+3=23x

4x - 23x = -3

-19x = -3

x = 3/19

comprobación:

4(3/19) + 3 = 23(3/19)

12/19 + 3 = 69/19

69/19 = 69/19

x-3=7x

x - 7x = 3

-6x = 3

x = -3/6

x = -1/2

comprobación:

-1/2 - 3 = 7(-1/2)

-7/2 = -7/2

9x•4=72x

36x = 72x

36x - 72x = 0

-36x = 0

x = 0

comprobación:

9(0). 4 = 72(0)

0 . 4 = 0

0 = 0
