Question

7)..... ecuaciones de primer grado


x - [3x - (2x - 1)] + 5 = 2 + [ 3(2x-3) ] 7 ) x - [ 3x - ( 2x - 1 ) ] + 5 = 2 + [ 3 ( 2x - 3 ) ]​

Answer 1

Respuesta:

Explicación paso a paso:

x - [3x - (2x - 1)] + 5 = 2 + [ 3(2x-3) ] 7 )

x - [3x - (2x - 1)] + 5 = 2 + [ 6x - 9 ] 7 )

x - [3x - 2x + 1] + 5 = 2 + [ 6x - 9 ] 7 )

x - [1x + 1 ]+ 5 = 2 + [ 6x - 9 ] 7 )

x - 1x - 1 + 5 = 2 +  42x - 63

x - x  + 4 = 2 +  42x - 63

4 - 2 +63 = 42x

2 + 63 = 42x

65 = 42x

65/42 = X
