Question

Respuesta con operación de 7/4-2x/5=x/2-1/3

Answer 1

Resolver.

7/4 - 2x/5 = x/2 - 1/3
7/4 + 1/3 = x/2 + 2x/5
21/12 + 4/12 = 5x/10 + 4x/10
(21 + 4)/12 = (5x + 4x)/10
25/12 = 9x/10
(25*10)/12 = 9x
250/12 = 9x
250/(12*9) = x
250/108 = x    Simplificamos sacamos mitad
125/54 = x

Solucion.
x = 125/54
