Given equation is .

Rewrite the equation in the form Ax + By = C.

Apply disributive property: .

                   (Multiply: )

    (Subtract y from each side)

    (Apply commutative property: )

        (Apply additive inverse property: )

              (Apply additive identity property: )

   (Add 4 to each side)

         (Apply additive inverse property: )

              (Apply additive identity property: )

                    (Add: )

The equation is now in standard form where A = 4, B = , and C = 7.

This is a linear equation.

Equation is a linear equation.
