Question

3x - ( x + 2 ) / 4 = 5x - ( 2x + 5 ) / 5

Answer 1

Respuesta:

x = 10/3

Explicación paso a paso:

3x- ( x + 2 ) / 4 = 5x - ( 2x + 5 ) / 5

[3x*4- ( x + 2 )]/4 = [5x*5 - ( 2x + 5 )]/5

(12x -x -2)/4 = (25x -2x -5)/5

(11x -2)/4 = (23x -5)/5

5(11x -2) = 4(23x -5)

55x - 10 = 92x - 20

55x - 92x = -20 +10

-37x = -10

x = -10/-37

x = 10/3
