Respuesta :

700+80 would already equal 780 so if you add 1, (left side would equal 781) (right side 780+1=781) so n=1

Answer:

The given equation is true for any value of n.

Step-by-step explanation:

The given equation is

[tex]700+80+n=780+n[/tex]

[tex]780+n=780+n[/tex]

Taking all the terms on the left sides of the equation.

[tex]780+n-780-n=0[/tex]

Combine like terms to solve the above equation.

[tex](780-780)+(n-n)=0[/tex]

[tex](0)+(0)=0[/tex]

[tex]0=0[/tex]

LHS=RHS for any value of n.

Therefore the given equation is true for any value of n.
