Question

What Is the evaluation of 8y - x?

Answer 1

See below:

Explanation:

We cannot simplify this because we do not have like terms. If we were told what `y` and `x` were, we could evaluate this.

Let's say that `y=6` and `x=7`. In this case, we would just plug these values into our expression to get

`8(6)-7`

This simplifies to

`48-7`, or `41`.

Once again, we cannot simplify this expression because we do not have like terms. If we are told the value of the variables, however, we can plug them in and evaluate the expression.

Hope this helps!
