The equation is .

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

           (Multiply each side by 4) \ \

    (Apply distributive property: ) \ \

              (Cancel common terms) \ \

                    (Multiply: ) \ \

  (Add 3x to each side) \ \

(Apply commutative property of addition: a + b = b + a)

                  (Apply additive inverse property: ) \ \

                         (Apply additive identity property: )

The equation is now in standard form where A = 3 , B = 4, and C = 8.

This is a linear equation.

Option C is right answer.
