Respuesta:
7X+1=57 => el "1" pasa a restar
7x=56 => el "7" multiplicando pasa dividiendo
x= [tex]\frac{56}{7}[/tex]
x=8
Explicación paso a paso:
[tex]\bold{7x + 1 = 57} \\ \\ \bold{7x = 57 - 1} \\ \\ \bold{7x = 56} \\ \\ \bold{ \frac{7x}{7} = \frac{56}{7} } \\ \\ \boxed{\bold{x = 8}}[/tex]
[tex]\bold{7(8) + 1 = 57} \\ \\ \bold{56 + 1 = 57} \\ \\ \bold{57 = 57}[/tex]
