Answer 2

14x (19x + 18) = x² + 7x + 1  

Incógnita: x

Primer Miembro: x + (19x+18)  

Segundo miembro: x² + 7x + 1  

Términos: 14x, 19x, 18, x², 7x, 1  

Grado: 2  

x+2 = 9 Solución x=7  

7+2= 9 Es compatible  

Un ecuación equivalente:

2x+4=18  

Observa que para obtener una  

ecuación equivalente se han  

multiplicado los dos miembros por 2.
