Question

Solve the following system of equations by the substitution method.x-y=0 x-y-2=0

Answer 1

No solutions

Explanation:

From the first equation you have that

`x=y.`

Substitute y instead of x into the second equation:

`y-y-2=0,\\ \\-2=0.`

This is wrong equality, so the system of two equations have no solutions.
