Question

(x-1)/3 + (x-2)/6 + (x-3)/9 = (x+4)/12

Answer 1

Respuesta:

X = $\frac{48}{19}$

Explicación paso a paso:

$\frac{(x-1)}{3} +\frac{(x-2)}{6} +\frac{(x-3)}{9} =\frac{(x+4)}{12}$

12(x-1)+6(x-2)+4(x-3)=3(x+4)

12x-12+6x-12+4x-12=3x+12

22x-36=3x+12

22x-3x=12+36

19x=12+36

19x=48

X= 48/19
