# How do you combine like terms in (t + 7) + ( 5t + 6)?

May 14, 2017

Answer: $6 t + 13$

#### Explanation:

We can only add/subtract terms with the same variable to the same degree. In this expression, $t$ and $5 t$ have the same variable to the same degree while $7$ and $6$ are both constants, so:
$t + 7 + 5 t + 6$
By rearranging:
$= t + 5 t + 6 + 7$
Note that $t$ is really $1 \cdot t$, so:
$= 6 t + 13$

Hope this helps.
