Given equations are,

----------(1)

---------(2)

The first equation is already solved for x,

So,  substitute for y in the second equation.

                 (Second equation)

        (Substitute  )

Apply distributive property: .

            (Multiply: )

            (Apply commutative property: )

                    (Apply additive inverse property: )

                          (Apply additive identity property: )

Generally, if you solve a system of equation s and the result is a false statement

Such as ,

There is no solution.

There is no solution.
