How do you solve the system x=10 +5y and 2x-10y=20?
Dividing the second equation by
this equation is identical to the first one.
There are many solutions because the two equations are just different forms of the same equation.
The equations given do not represent a system of equations because the one is just a different form of the other.
There is no single or unique for an equation which has two variables, but rather there are infinitely many solutions.
In this case, any value can be chosen for
A few possible solutions are:
