Question

How do you evaluate the expression 3x + 7x + 2 for x=6?

Answer 1

The answer is `62`.

Explanation:

First of all, it's useful to simplify the expression: you can sum the terms with `x`, obtaining `3x+7x=10x`. So, your expression becomes `10x+2`. Evaluating this expression for `x=6` simply means to substitute "`x`" with "`6`".

So, `10x+2` becomes `(10 * 6) + 2=60+2=62`.
