X +Y = 540

X= 3*Y + 88

...................

3Y +88 +Y =540

4Y +88 =540

4Y= 540 -88

4Y= 452

Y=452/4

Y=113................X=540-Y

                              X=540-113

                               X=427

540=(88+3x)+3x

 

540=88+3x+3x

 

540-88=3x+3x

 

452=6x

 

\frac{452}{6}=x

 

75,33=x

 

Ent: X1=88+3x=314

       X2=3x=226

 

Espero q te sirva!!!
