Question

(x-29/31)+18/31=1 17/31

Answer 1

(x-29/31)+18/31=1 17/31

х-29/31=1 17/31-18/31

х=30/31+29/31

х=59/31=1 28/31

Answer 2

$(x-frac{29}{31})+frac{18}{31}=1frac{17}{31}$

 

$x-frac{29}{31}+frac{18}{31}=frac{48}{31}$

 

$x=frac{48}{31}+frac{29}{31}-frac{18}{31}=frac{48+29-18}{31}=frac{59}{31}=1frac{28}{31}$
