Let x, y, and z represent three real numbers. write an algebraic expression to represent the difference obtained when twice x is subtracted from z.

Answer with explanation:

It is given that, x , y and z are three real numbers.

We have to make an Algebraic Expression ,when twice of x is subtracted from z.

Twice of x is equal to = 2 x

Twice of x when subtracted from z can be written as= z - 2 x

So, The required Algebraic Expression is:

    y=z -2 x
