Question

$\frac{1}{3}x -x = \frac{1}{4}x + 1$

Answer 1

Respuesta:

(1/3)x-x= (1/4)x+1 ; m.c.m ( 3 , 4 ) = 12

12(1/3)x-12(x) = 12(1/4)x+12(1)

(12/3)x-12x = (12/4)x+12

4x-12x = 3x+12

-8x = 3x+12

-8x-3x = 3x+12-3x

-11x = 12

-(-11x) = -(12)

11x = -12

(11/11)x = -12/11

x = -12/11

Comprobación :

(1/3)(-12/11)-(-12/11) = (1/4)(-12/11)+1

(-12×1)/(3×11)+12/11 = (-12×1)/(4×11)+1

(-12)/(33)+12/11 = (-12)/(44)+1

(-12÷3)/(33÷3)+12/11 = (-12÷4)/(44÷4)+1

(-4)/11+12/11 = (-3/11)+1

(-4+12)/11 = (-3/11)+1 ; 1 = 11/11

8/11 = (-3/11)+11/11

8/11 = (-3+11)/11

8/11 = 8/11

R// El valor de " x " es -12/11 .
