In Exercises 51-56, x, y and z represent the weights of the three ingredients X, Y, and Z in a gasoline blend. Say which of the following is represented by a linear equation in x, y, and z, and give a form of the equation when it is.The weight of ingredient X is the product of the weights of ingredients Y and Z.

To determine

If the condition forms a linear equation in x,y,z. Also, give the form of the linear equation if possible and here x,y,z represent the weights of three ingredients X, Y and Z in a gasoline blend. And the weight of ingredient X is equal to the product of weights of ingredient Y and Z.

Explanation

Since x,y,z representing the weights of three ingredients X, Y and Z in a gasoline blend.

It is mentioned that the weight of ingredient X is equal to the product of weights of ingredient Y and Z.

Therefore, it can be rephrased as:

x=y(z)<
