Question #1c521

Oct 21, 2016

$10 x + 3$
They are unlike terms and cannot be added.

Explanation:

There are often errors in the wording of a question, in particular, 'Solve' is often used instead of 'simplify'.

'Solve' should be used for an equation.
'Simplify' is used for an expression.

I took the liberty of changing the question from 'solve' to 'simplify'.

This type of question is often given when students are first learning algebra, to emphasis the following:

• only LIKE terms can be added.
• in algebra, an answer can have more than one term.

Students are often tempted to offer a single term as an answer in algebra, because in their experience, that had always happened.

$10 x + 3 \text{ } \leftarrow$In this case, there are two terms.

They are not like terms, so they cannot be added.
There is no simplifying to be done.
