Respuesta:
3x+2y=28 y=14 - 3x
4x+y=24 y= 24 - 4x
14 - 3x = 24 - 4x
-3x + 4x = 24 - 14
x = 10
Verificacion:
3x + 2y = 28
3(10) + 2y = 28
30 + 2y = 28
2y = 28 - 30
2y = -2
y = -2/2
y = -1
3(10) + 2(-1) = 28
30 - 2 = 28
28 = 28
Explicación paso a paso:
" Life is not a problem to be solved but a reality to be experienced! "
