Respuesta:
1.DESPEJAS X EN AMBAS ECUACIONES
5X+2Y=11 2X-3Y=12
5X = 11 - 2Y 2X = 12 - 3Y
X= 11 - 2Y /5 X = 12-3Y /2
2. IGUALAS AMBAS ECUACIONES
11- 2Y/5 = 12-3Y /2
3. RESOLVEMOS LA ECUACION
10 ¨ABRES CORCHETES 11- 2Y/5 = 12-3Y /2
2(11- 2Y) = 5(12-3Y)
22 - 4Y = 60 - 15Y ---- -4Y-15Y = 60-22
-19Y = 38 --- Y= -2
4.SUSTITUIMOS PARA HALLAR X
X =11- 2Y/5
X= 11-2(-2)/5
X= 11+4/5 ---- 3
X=3 Y = -2
Explicación paso a paso:
" Life is not a problem to be solved but a reality to be experienced! "
