2x+6x

The expression you provided, \(2x + 6x\), is a simple algebraic expression that combines like terms. Like terms are terms that have the same variable raised to the same power.

To simplify this expression, you simply add the coefficients (the numerical parts) of the like terms. In this case:

\(2x\) and \(6x\) are like terms because they both have the variable \(x\) to the first power.

Combine them by adding their coefficients:

\(2 + 6 = 8\)

So the simplified expression will be:

\(8x\)

The simplified form of the expression \(2x + 6x\) is \(8x\).
