Question

x - 5x/3=4x - 3/5 comprobacion

Answer 1

Respuesta:

x = -9/70

Explicación paso a paso:

x - 5x/3 = 4x - 3/5

x - 5x/3 - 4x =  - 3/5

-3x - 5x/3 = -3/5

(-3*3x - 5x) / 3 = -3/5

(-9x - 5x) / 3 = - 3/5

-14x/3 = -3/5

x = 3*3 / 14*5

x = 9/70

x - 5x/3 = 4x - 3/5

-9/70 - 5*(-9)/3*70 = 4(-9/70) - 3/5

-9/70 + 15/70 = -36/70 - 3/5

6/70 = (-36 - 3*14)/70

6/70 = (-36 + 42)/70

6/70 = 6/70

3/35 = 3/35
