x=2+6 ................x =2(y)+6.......... x =2y+6.............x=2y+6
y y y y y y
2(x+y)=5(x-y)+8.........2x+2y=5x-5y+8..........2x-5x+2y+5y=8........-3x+7y=8
sustituimos x=2y+6 en la segunda ecuacion
-3x+7y=8
-3(2y+6)+7y=8
-6y-18+7y=8
7y-6y=8+18
y=26
si y=26
x=2y+6
x=2(26)+6
x=52+6
x=58
los numeros son 58 y 26
